Another British Military watch on the blog this time, and something of an enigma. The watch is very similar in style and size to the W10 made by Hamilton from and subsequently by CWC from and it shares all of the attributes required to adhere to the strict standards for military use. The case is opened by removing the crystal and splitting the two-piece stem, and inside is a 17 jewel, manually wound calibre made by A. It has a higher beat rate, 28, bph as opposed to 21, bph, and also has a micro-adjustment mechanism mounted on the balance cock for more accurate regulation. Here is a picture of a cal. In the picture above, the stem is pushed all the way in — in the winding position — and so the stem presses on hacking lever, it pivots around the fixed axis just above the castle wheel and the lower arm of the lever releases the balance allowing it to rotate freely. The watch arrived in decent condition and needed no more than a movement service, a crystal polish and an ultrasonic clean for the case, so here it is all back in one piece. So, who made these watches? With no markings on the dial, movement or inside the case, the jury is still out.
Vintage Omega watches from the golden period when the company still manufactured its own movements in-house are one of our specialities. The quality of Omega production pre s was extremely high and compared side by side, there is no doubt at all that the mechanisms in these models are every bit the equals of those by Rolex, IWC, Jaeger LeCoultre and the other top tier Swiss makers. In our business, we have said for years that classic Omega models offer Rolls-Royce quality at Jaguar prices and we always strongly recommend them to our customers.

Rolex watches feature two sets of identification numbers On modern Oyster cases excluding the OysterQuartz , these numbers are engraved between the lugs, hidden behind the end pieces as shown in the images below. A close-up view of the same watch, you can clearly see the Serial Number “F “, engraved into the case at the 6 o’clock position, with “ROLEX” engraved repetitiously around the dial in a circular fashion.
In , Rolex began issuing every Rolex Oyster case a unique serial number to distinguish them from one another. This numbering system was originally believed to have started at 20, , however earlier numbers have surfaced shooting holes in this theory. Around , the numbers reached the , mark, at which time Rolex decided against adding a 7th digit, thus continuing into the “millions”–Instead, they started the sequence over.
While it was originally believed that this resequence started over at , , or even 20, , but evidence suggests that it actually restarted at 10, or possibly lower.
Omega serial numbers: How old is your Omega watch?
Where to find an Omega watch’s serial number Each and every Omega watch has a unique seven- or eight-digit serial number, which is etched into its case during production. The location of the number depends on the age of your timepiece, as the company has used several locations over the years. If you have an Omega watch that was manufactured recently, there is a very good chance that you will find the serial number on the back of the watch.
This chart is in no way a substitute for contacting Omega Vintage Information with the Serial Number of an Omega movement and requesting information as it is a very inexact guide. However it is useful for narrowing down the vintage of Omega Watches (perhaps as close as +/- years).
Pros and Cons Rolex Case Back Stamps Used Inside Vintage Rolex Watches One of the things that are so rewarding about this website is the ability to compile data over a long time period and present it in a way that has so far not being available to collectors, either in book form or online. Here, it should be possible to identify a subject and create a pool of knowledge relating to it, forming a lasting record that enthusiasts can keep returning back to whenever they wish.
As far as we are aware, nobody has ever tried to put these into strict chronological sequence before, so this exercise is venturing into uncharted territory. Hopefully, it should be useful as an aid to weeding out those watches that have wildly different case back markings to others from the same year, this suggesting that they merit further scrutiny to confirm their originality. It seems most logical to structure this section so that the chart itself is accessible with a minimum number of clicks in order that returning browsers can refer back to it in the most direct fashion.
However, it is the first form of case back marking used by the company that would go on to become Rolex, hence it makes a logical point at which to begin this research. The next era of vintage Rolex case back stamping is the most relevant to the project being undertaken here. In the early s, Rolex introduced a new case back signature on which the number of world records set by the company in accuracy competitions was stated below the Rolex brand name. In our business, we have long believed that if this rising number was accurately charted by year, it would be a useful dating aid that could be of assistance to the collector in instances when other means of identifying a specific year of production, i.
Similarly with early Rolex Oyster cases, there should be a pattern of increasing patent numbers mentioned as the years go on. Later, the mention of patents by number and individual country would be dropped but even so, Rolex gradually evolved its case back stamps and it should be possible to pick out some sort of trends. In the early s, a system of date stamping was introduced for Oyster cases, with the quarter of the year in which the watch was produced indicated by a Roman numeral, after which the last two digits of the year were given in Arabic numerals.
So, for instance, II. Again, hopefully the process of recording case back stamps in this way should allow us to spot any other variations that exist from this period.

Among the first companies to sell wristwatches, the Gruens split their manufacturing between two continents, exporting American technology to Germany and Switzerland, and bringing German and Swiss traditions of craftsmanship to America. Dietrich was born in Osthofen, Germany, in , and started his watchmaking career at age In he went to America and settled near Columbus, Ohio. A hard-working young man, Dietrich was awarded his first watchmaking patent at age 27, in At 29 he co-founded the Columbus Watch Manufacturing Company; the successful enterprise was soon building complete watches in its own employee factory buildings.
To graduate, Fred was given bars of metal from which he had to build working watch movements, designing and manufacturing all the parts. Initially, Dietrich and Fred designed the watch movements in America and manufactured them in Germany. Later, they would build their own movement factory in Switzerland. Most Gruen watches have Gruen-made Swiss movements and were assembled and adjusted in the U.
Pocket watches in the late s were large and heavy. Throughout his career, Dietrich tried to make his watches smaller, thinner and more comfortable to carry in a vest pocket, without sacrificing reliability or accuracy. The Gruen VeriThin pocket watch was a major breakthrough; although it had the same major parts as a traditional movement, Dietrich managed to rearrange components to achieve a much thinner watch.
From this point on, Gruen specialized in thin, elegant pocket watches.

Omega Serial Numbers and Production Dates Note that Omega began using ETA movements in some of its watches in about This table does not include accurate dates for Omega/ETA movements.
This is probably the most common question watch collectors have. Sometimes it is easy to answer, and sometimes it is impossible. There have been a lot of watch manufacturing companies that have come and gone over the years. Many have gone out of business, while others destroyed records to save space. Some companies as with the Gruen Watch Company , even lost rocords to fire or other natural disaster. The companies are not to blame. I am sure they had no idea that their timepieces would someday be collected.
There are several ways to get an idea of when your watch was made. I am slowly adding serial number tables to this site. Serial number records are available for many of the old pocket watch companies like AM Waltham, Elgin, South Bend etc.
Fractale was conceived as a way for its director, Yutaka “Yamakan” Yamamoto, to make Kyoto Animation regret firing him, with all the resources put into it that you’d expect with a goal like that. He was so sure of its success that he said he’d step down if it did poorly. The end result was said to be good, if not great, by most people who watched it to the end, but not many people did. Yamakan probably would have had to step down even if he hadn’t explicitly staked his career on it doing well.
The main problem was the competition; Fractale was billed as the “moe-killer” series by the director himself, and as if to prove this it was released at the same time as a cutesy-looking Magical Girl show. Unfortunately for Fractale that show was Puella Magi Madoka Magica , which proved to be the anime for the Winter season.
Date your Omega Watch by the serial number on the case. Omega History and production dates here.
First check the inner rim of the watch face also called the rehaut, which is french for “flange” between the dial and the crystal. If the watch was produced in or newer the serial should be engraved on the rehaut. On older Rolexes, this serial is located on the side of the watch case at the 6 o’clock position where the bracelet is attached. To view these serial numbers, the bracelet must be detached from the 6 ‘clock side of the case.
For instructions on removing the bracelet, see the video to the right or call us at to speak with a Rolex expert. You can also learn where to find Rolex serial numbers here. As with the serial number, the bracelet must be detached from the 12 o’clock side of the case to be able to check the serial number. For instructions on removing the bracelet, watch the video above or call us at to speak with a Rolex expert.
The production age of a pre-owned Rolex watch is a significant factor in determining its current market value. As you would expect, the value of a Rolex watch, unlike a fine wine, will decrease in value as new, improved models are launched by Rolex.
