I can provide you with the numbers above mentioned, a perfect match can be found. It is much easier to replace either for original brand or the generic. My advice: do not try to fix these movements, it would take considerable skill and time. Same goes for citizen 5R12, 6L12 and others. With Seiko and Citizen the identification is on the back of the watch, sometimes in the bottom of the dial, and most definitely in the movement, like VX42, V810 and so on. Seiko use Hattori movements that are interchangeable and Citizen uses Miyota movements. They make all kinds of watches, some of them mostly for the Japanese market very costly. Japanese movements, Seiko and citizen are the largest watch companies in the world. Well the bridge is the watch fingertip, unique to each individual, so there are books with watch illustrations about this bridge, you can match it there. There is another way to identify a movement if for some reason no lettering can be read or found, under the dial is the bridge, the funny looking parts that hold the setting parts, looks like an alien hand if you had some imagination. But the principle goes for all the movements, all of them are marked on the back either by movement company or the watch company.
I mentioned ETA because is the largest of the Swiss companies there are also Rhonda FE, ISA. Sometimes the movements are discontinued due to the age, but you still can get parts, so you can clean the old ETA movement and order a coil, a circuit or both to make that special watch work again. The calendar wheel can be replaced, so if you do not find the same movement with the calendar at 6 o’clock, you’ll have to remove the old calendar wheel and replace it in the new movement. Also be aware of how thick the dial is, because sometimes the same movement has a long and short center shaft (canon pinion). If it has a calendar window, is it located a 3 o’clock 4 o’clock 6 o’clock. When you are ready to work in a watch, you should consider if the watch has a seconds hand, if the watch has a calendar window.
Some watchmakers would use their own nomination and should be crossed reference with standard ETA. If you need parts or a new movement, sometimes the identification is located by the battery, sometimes in one corner by the coil, sometimes it is in the circuit board. That number would be your reference number. It is the glassy red dot where the pivot of the wheel sometimes goes through. 955-114, 2001-001 also will tell you how many jewels if there are any. Japanese watch movements are sometimes are more costly than Swiss watch movements, but it is lesser quality and it’s difficult to work on a movement made of plastic.Ī Swiss movement will have stamp of 3 letters – E.T.A. Swiss watch movements are better quality and normally have a higher labor rate for repair. Sometimes it is hard to tell them apart, especially in the low grade, and in the very high end. For example: F10Y would be broken down to October, 2006.Open a watch and look inside, you are looking at either a Japanese watch movement or a Swiss watch movement.
#How do you tell seiko model number code#
This code does not reflect the date of manufacture. The fourth digit/letter identifies the factory code.The second two numbers specify the month, from 01 to 12.The first letter identifies the year, from A to Z.Powersport Batteries Product Date Codes The first four characters represent the year, month and production line(Y/MM/*) These are internal lot numbers or injection mold numbers and they have no bearing on the date of manufacture. For example: 09016 would be broken down to September 1st, 2006 There may be additional alpha-numeric characters at the end of the date code. The fifth digit identifies the year from 0 to 9.The second two numbers specify the day of the month, from 01 to 31.For example, March is 03 and November is 11. The first two numbers identify the month, from 01 to 12.
