After ensuring that you have a nice grip, slowly rotate it counter-clockwise until it screws back in to place. In general, for all time periods, it is important to understand that Bulova watches never provide an obvious date of manufacture anywhere on the watch. Accutron: The World's First Electronic Watch Beginning in 1952, Bulova began exploring and developing technologies that would create the first revolutionary change in timekeeping technology in over 300 years: the Accutron. The serial number may be located anywhere on the mechanism, so, be very careful when doing this, because even a tiny misstep at this stage could be enough to damage the Bulova beyond repair. There are actually at least five currently known exceptions to that rule, and the list keeps growing as more watches are studied. All factors discussed here should be considered together to make the best possible date assessment.
Below is an example of a 1926 watch, where the year of manufacture has been determined using both the symbol on the movement and the matching serial number, along with an examination of the watch's characteristics. These must have been the first years that Bulova implemented it's new dating system. Therefore, going the cautious route however slow it may be is the perfect way to go. While there are plenty of ways to skirt around the supposed bad eggs, the serial number lookup will probably be the most efficient and reliable one of them all. Since 1948, Bulova watches have a two-number code on the back indicating the year the watch was made. Ultimately, the Omega Speedmaster Professional was chosen, but Accutron movements were used in instrument panel clocks and other timing instruments on the spacecraft itself, and in experiment packages left on the surface of the moon. This is my article on Bulova watches serial numbers lookup.
While it is not entirely foolproof or secure we are talking about high-end fakes after all it would certainly be a great idea if you can find the time to perform a Bulova watch serial numbers lookup whenever you intend to make a purchase. Sometimes it is easy to answer, and sometimes it is impossible. Not all vintage watches can be dated using the serial number. The first digit indicates the decade and the second indicates the year. With some models though, there will be an additional protective cover over it, which can usually be pried off with a fingernail or a rather dull tool. More than one name may appear on the movement.
Unlike models from the 1950s, these 1940s ladies' watches do not have a case date code, so the only way to date the watch is by the movement symbol. Therefore, any watch with a movement dated more than one year later than the case is assumed to be a replacement movement. Additionally, in many instances, the case serial number on these later models can be used as a date reference. When purchasing a watch, I check both the case and movement date, and if they are more than one year apart, I assume that the movement is not original to the case. See my section on to learn how to get inside your watch. The company was also very innovative with its advertising and marketing. If there is no two symbols, it could be that your watch was made before 1948.
Dating a watch this way requires opening the case and noting every detail of the movement and case and then comparing those details to the list below to see where the watch best fits in the timeline. On the top floor of the Observatory an expert mathematician took readings that were simultaneously recorded on a chronograph located in the lower floors of the building. I do believe that the case is by far the most important factor in determining both the date and model of the watch, and all other factors are to be considered but do not necessarily control the outcome, because all other factors--movements, hands, dials--can be changed. The fall of a giant Before they closed their shop in 1977 due to falling sales and the threat posed to them by cheap Japanese made quartz movements, they had made and sold a whopping 4 million units of Accutron wristwatches up until that point. It is important to note that both the movement code and the case serial number provide only a year within a decade, but they do not give any clue as to the correct decade. The cases themselves are made from high-grade stainless steel, and the dial hands on them are tinted luminous to better facilitate its nighttime visibility. Additionally, I have some late 1970s models that bear no date identification that I can determine.
Do be aware that some symbols were used more than once over the years. Well, a true blue Bulova watches serial numbers lookup may help you do just that. Moreover, these are no longer using the tuning fork movement system that had defined the accuracy of its predecessors for so long in the past. If more than one year separates the movement and the case, for me, the case date rules. Looking at the table of Waltham serial numbers see example below , you can see that number 20,900,000 was made in 1917 and 21,800,000 was made in 1918 marked in red in the table below. A typical example of a 1930s solid gold model with no case serial number can be observed here:. While I admit that the brand is not exactly on the high-end spectrum, they do, however; offer some absurdly great watches within their ranges.
What makes the precisionist so amazing? What this does is that it gives the precisionist its unsurpassable level of accuracy, as well as the stunning smooth movements of its second hand. Modern Bulova Watches To the best of our knowledge, the Bulova brand is currently owned by Citizen who still produces watches under the Bulova name. For one thing, there is no particular model number or figure code etched on its outer frame. There is a silver lining about it though, the Date code system that had existed back then sported a very different format — they used symbols instead of numbers, as I have shown in the chart given below. The Bulova company was founded in New York City in 1875 by Joseph Bulova, who had recently immigrated to the United States from Bohemia.
Moreover and to a lesser extent, some of the other things like the dial features, how the main dials are shaped, and the placement of sub-dials if any can also serve as rather strong indicators to help you determine the make of your Bulova model more precisely. There are several ways to get an idea of when your watch was made. The school also housed an extensive horological library, recreation facilities, and a full kitchen and dining room. Going hunting on a Bulova watch to find the ever-elusive Serial numbers can often turn out to be a rather risky business, especially if the Bulova in question is a vintage piece or a rather old one. This is probably the most common question watch collectors have. The Elgin and Hamilton were dated by serial number, while the Gruen was dated by an inscription on the back. With these ones, you should see a set of six grooves or notches set against the perimeter of the central backplate.
If your watch is damaged so that you cannot see any names or number codes, you may need to seek the assistance of a watch dealer or watch professional at a jewelry store that carries fine watches. I am sure they had no idea that their timepieces would someday be collected. Avoid using a sharp object like a knife though, and even if you were to use one, always show some restraint with it. Cases and watches were often made by different companies and each usually has its own serial number. However, it is important to note that all such movement lists are based on observations of examples rather than any official Bulova documentation.
