BRIEF HISTORY OF ORIENT WATCHES

Orient Watch was founded in Tokyo by Shogoro Yoshida, more than a century ago in 1901. And though the world was a very different place back then, everyone still needed to know what time it was – much like today’s world.

In those early watch making days, Orient Watch had some competition in the watch industry at home. Seiko and Citizen were big names in the watch making industry, and for many years Orient was ranked number three when it came to watch companies.

From the early beginnings, Orient Watch has been focused on making the best mechanical watches that money can buy. The history of Orient Watch is interesting because Orient Watch is a company that started out with a good idea, and never once veered onto a different course. The long years have helped Orient Watch to produce high-quality, long-lasting watches that anyone can afford.

In 1985 Orient and Seiko established a joint factory. Orient produces a range of automatic and quartz watches ranging in price from reasonably inexpensive (about 50USD / 50Euro) to very expensive (7000USD). Orient Star and Orient Star Royal are the middle and high-end brands, with the Royal Orient being their flagship line." - quoted from Orient Watch Company, Wikipedia

Today, Orient Watch is known all over the globe. With manufacturing facilities in Singapore, Brazil, and Japan, Orient Watch today offers more styles and types of watches than ever. Today, Orient Watch offers watches in many designs including quartz, light powered, and of course mechanical.

Mitsuo Mimura, President of Orient Watch in 2006 quoted in Orient Watch website “In the Japanese market, we supply high-quality watches, such as "Orient Star Royal," our prestigious mechanical watch series, which our customers want to carry with them for many years. In overseas markets, our strategy is to develop new outlets for our products mainly in countries and areas with high potential economic growth, and increase our sales of budget-price watches."

For more than a hundred years, Orient Watch has been a well-known and respected name in the watch making industry. Today, many other companies try to reach the success and the high standards that Orient Watch has set. When it comes to mechanical watches, Orient Watch is the first name in the business. For high quality at an affordable price, Orient Watch is one of the better choices in watches. But don’t just take my word for it. Let the history of Orient Watch speak for itself.

Rado is a Swiss manufacturer of watches, with headquarters in Lengnau, Switzerland. It is noted for its use of scratch-proof materials, a field in which it is considered a pioneer. Today the company produces about half a million watches a year with a staff of about 300 in total.

Formed in 1917 as Schlup & Co., Rado initially produced watch movements only. In 1957 the company launched its first collection of watches under the Rado brand. In 1962 the Rado Diastar, the world's first scratch-proof watch, was launched. It has been in production ever since, now sold as DiaStar The Original.

In 1983 Rado became part of the SMH group which was renamed in 1998 as the Swatch Group.

RADO differs from the traditional Swiss watch makers in that it leans towards innovative uses of high tech materials in distinct design. RADO has focused on pioneering the use of a number of materials that are unique within the watch making industry, such as e.g. hardmetal (tungsten and titanium carbide), ceramic, lanthanum and sapphire crystal.

In 2004 the RADO vision was realized with the introduction of the V10K. Coating the watch with high tech diamonds made the V10K the hardest watch on Earth, realized by the Guinness Book of World Records.

The newer RADO watches are also distinct from the traditional Swiss watch industry in that their aesthetic is unique. Market reaction tends to be mixed to such a strong aesthetic, with many who appreciate the unique and distinct RADO look and those who do not.

During their time, RADO has received more than 20 elite international design awards, from the RED DOT Award to the iF Design Award, for both their product and most recently, their collaboration with Jasper Morrison for an innovative watch box that mimics the shape of the human wrist.

AUTHENTIC OMEGA DE VILLE DYNAMIC GENTS WRISTWATCH (SOLD)





BRIEF INFORMATION ON OMEGA DYNAMIC

Its elliptical shape results from an advanced study of the anatomy of the wrist and specifically the oval zone on which the wristwatch rests. Self-winding movement. Monocoque case, hermetically sealed crystal assuring water-resistance to 30 m. Dial in harmony with the decidedly functional look of the watch for easy legibility of the hour, the minute and the second thanks to concentric time "zones" and contrasting coloured hands. A new look to the bracelet too: a single piece screw-in into a circular groove under the case by a steel ring; cut in Corfam, a porous synthetic material pierced with 30 aerating holes; widened near the case to fit firmly and comfortably on the wrist. Crown integrated to the case in order not to break the aerodynamic line which inspired this famous model's name.

History of Omega Watch Co

The History of a Successful Company Omega was founded by Louis Brandt at La Chaux – de – Fonds, Switzerland in 1848 as a assembly workshop. In 1879, after his death, his two sons Louis Paul and César started the in-house manufacturing so they started having total production control. One year later, Omega moved into a small factory that became a huge one when 12 months later they bought the entire building. In 1903, they both died leaving the company in 24 years old, Paul Emile Brandt’s hands. Because of the crisis that the Second World War left, he had to work really hard in order to face the economic difficulties. He merged Omega with Tissot calling the new company SSIH. The SSIH group continued to grow and multiply under his leadership and, by the seventies, it had become Switzerland’s number one producer of finished watches and number three in the world.

In 1985, the holding company was taken over by a group of private investors under Nicolas Hayek leadership. It was immediately renamed SMH (Société suisse de Microélectronique et d'Horlogerie). SMH had a rapid growth and success becoming today's top watch producer in the world. Named Swatch Group in 1998, it now includes Blancpain and Breguet.

A History of Rolex Watches

Hans Wilsdorf founded the company we now know as Rolex in 1905. Born in Kulmbach, Germany in 1881, the company, Wilsdorf & Davies, was based in London. By 1908 it had become one of the leading watch companies in the UK. It was in this year that he coined the name Rolex.

Official Chronometer Certification was awarded to Rolex in 1910 from the "Bureau Officiel" in Switzerland, the first time this had ever been given to a wristwatch. This was to be the first of many accolades awarded to the watch, including the Class A Precision from the Kew Observatory in 1914.

In 1926 the Rolex Oyster was released. It was the first wristwatch to be considered waterproof, proven a year later when the watch was worn by the swimmer Mercedes Gleitze in his successful bid to cross the English Channel. This was beneficial to Wilsdorf whom had sponsored the event and gained considerable exposure for his new Oyster Watch. Wilsdorf recognized the importance of advertising and marketing his creation in order to gain publicity and prestige. 1931 saw the creation of the Perpetual Rotor, a mechanism now seen as the basis for self-winding movements. In the following years Rolex released the first Oyster Perpetual Lady-date (1954) the GMT Master with dual time zone function (1955) and the first Day-Date (1956).

Andre Heiniger took over the company following the death of Hans Wildorf on 06 July 1960. Rolex continued to invent and innovate in terms of technical skill and style throughout the 2nd half of the century. The Sea-dweller (1967) was certified as reaching depths of up to 1,220 meters making it the choice for Professional Divers - a point that was quickly adopted in advertising the model. The Explorer II (1978) and Cosmograph Daytona (1988) were also released to international waiting lists securing Rolex as one of the worlds most prestigious watch brands.

AUTHENTIC MARATHON MIL-PRF-46374G Watches Mechnical 17 Jewels Swiss Manual Winding with Hacking System






MIL-PRF-46374G Watches Mechnical 17 Jewels Swiss Manual Winding with Hacking System

With MIL-PRF-46374G a new idea in U.S. Military purchasing was introduced, the Performance Standard. The military no longer specifies endless detail on the design of the watch, they just state what performance tests it has to meet. This gives manufacturers more leeway to be innovative and hopefully gets a better product for the troops at lower cost. Note that some watches under the prior standard have been procured this way, under MIL-PRF-46374F.
In the G standard, issued 12 November 1999, the most noticeable change is on the dial where all extraneous markings have been removed. Only the H3 and radiation symbol remain so users can focus on the hands and numbers. The case back has similar markings to earlier models.
Under MIL-PRF-46374G, the Navigator watch is now called Type III, Class 1, new terminology for the Type 6 of the prior standard. Typical markings for these watches:
WATCH, WRIST: GENERAL PURPOSE
MIL-PRF-46374G
6645-01-304-4306
26 MILLICURIES
NRC ID: 54-28526-01E
SPO440-05-D-0160-005
JUNE 2006
CAGE 38775
The CAGE Code refers to Marathon. Some watches of lower grades have been produced by reference to MIL-W-46374G, not a performance spec. In 2000, Stocker & Yale withdrew from the military watch and compass business and sold that division of the company to Cammenga & Associates, Inc. a maker of the U.S. Army Lensatic Compass among other products. Cammenga later stopped making watches leaving Marathon the sole supplier of watches to the U.S. Military.

BRIEF INFORMATION ABOUT TEGROV WATCHES

Perrin, Charles
is also a brand name or model name used by, Werner Schaub, Tegrov Watch, Tennekin. He was also involved with Fabrique D'Horlogerie Tenniken. Werner Schaub bought the Groflin factory to produce deluxe watches sold under the Charles Perrin name.

Tegrov was listed as a brand of Groflin in 1951 and 1966 and were associated with Roskopf watches and pin levers. Most of Tegrov used 17 jewels calibre EB suplied by Roskopf.

Tegrov (aka 'von Tegrov') was a fairly generic Swiss brand in the 1960s-70s. That have been a claims of a Russian connection, but they are entirely spurious. Researched found that there were Sicura or Sorna link as they seem to favour the same extreme funky multi-function thing.

History of the Omega Speedmaster
The first chronograph with the name "Speedmaster" appeared in 1957. And that is pretty much the same Speedmaster as we know it today. On first sight.
Through the years, a lot of things were changed on this watch. For instance, the word "Professional" in 1966 when it was approved for NASA use (more on that later), in 1968 they (Omega) changed the movement from a calibre 321 (with "schaltrad") to a cheaper to produce, but more accurate calibre 861 (with shuttlesystem). Both movements were based on Lemania movements. Todays Speedmaster Professional watch still uses the 861 movement. Before 1957, there were also some chronographs (since 1942) using the 321 calibre but they had no "Speedmaster" written on the dial.
The first Speedmaster (1957) looked like this :
First  Speedmaster
Foto scanned from Time Capsule
This model, referenced as CK2915 was created in 1957 and is nowadays hard to find. The watch has the 1/5th seconds, minute and hours markings in white on a black dial. The counters are located on 3 o' clock, 6 o' clock and 9 o' clock. The bezel contains engraved tachymetre figures (not very clear on the photo above).
The caseback is the one with the Seamaster logo because this type of watchcase was originally developed for the Seamaster (triple-shield case to enable it to withstand high pressure). The diameter of the watch-case was 39mm.
The movement used in this watch was a 27 CHRO C12, better known as the Cal.321 (manual winding).
The 27 stands for 27mm, the CHRO stands for "chronograph" and C12 indicates that the watch has an 12-hour counter (at 6 o'clock).This movement was designed by Albert Piguet (who worked for Lemania during those days) in 1942. It took Omega 15 years to produce this watch as it was released in 1957.
In 1959 they produced a slightly modified Speedmaster, known as CK2998. The watch-case diameter expanded from 39mm to 40mm and they added a so called O-ring gasket around the push buttons.
Speedmaster  CK2998
CK2998
Until 1966 there were no big changes on the watch (look for the "Differences through the years" in the menu for details). The NASA bought a Speedmaster along with some other chronograph watches to test it for use on their missions. Read all about it in the "Nasa tests" section of this website. After long and rigirous testing of the watch, the NASA concluded that the Omega Speedmaster was the most suitable watch for 'the' job. Omega decided to make this watch the Omega Speedmaster Professional. So the word "Professional" was added but it was still the same watch. The watch got also the 145.012 reference number. There are also watches from 1966 with 145.003, these are the non-Professionals from 1966.
In 1968, Omega decided to replace the cal.321 movement by a more accurate movement which was also cheaper to produce, the cal. 861 which was also produced by Lemania. This movement is still being used in the current line of Omega Speedmaster Professionals. The movement was a bit more accurate, 21600A/h instead of 18000A/h. It also uses a shuttle cam instead of a "schaltrad" for the chronograph. Changes on the outside : white marked Omega-symbol instead of metal applied Omega-symbol and a flat dial.
Speedmaster
In 1969, the first man walked on the moon.. Neil Armstrong. He didn't wear his Omega Speedmaster Professional. The clock inside the Lunar Module went broke, and he hung his Omega Speedmaster Professional in the Lunar Model as a clock-replacement. Buzz Aldrin, he did wear his Omega Speedmaster Professional. So his watch was the first watch worn on the moon. It was a Omega Speedmaster Professional with a cal. 321 movement (confirmed by Omega). A few months after the landing on the moon, Buzz's watch was stolen and never returned.
In 1978, the watch was produced with an engraved caseback. "Fligt Qualified by NASA for all manned space missions - The first watch worn on the moon". Some casebacks have another text or logo engraved, No explanation at this time.
