OMEGA SEAMASTER SERIAL NUMBER DATE PRO

The parts bin could conceivably contain bridges manufactured and numbered in 1996, or any year since, creating the possibility that a movement assembled in 2008 might have a bridge number dating from 1996. 1863 has been in production since the mid-1990s. Obviously, the parts bin may contain a mixture of bridges produced over the years a particular movement was produced. It may be some time (even years) before an assembled movement is installed in a case. No one takes the time or the effort to insure 'first in, first out'.

Again these movements are randomly pulled for installation in the cases. Once assembled, the movements are 'put on the shelf' for later installation in the cases. Note that this selection process might permit a bridge to sit in a bin for years before being used. No one takes the time to remove them from the bins in order i.e., first in, first out. As they are machined and engraved, these individually numbered bridges are collectively placed in parts bins awaiting assembly into the movements.ĭuring the assembly process, these numbered bridges are randomly selected from the bins and installed along with the other parts. (On later model Speedy Pros, this number is also engraved on the back of the 7:00 lug.) Most refer to this as the movement number but more accurately, this number should be called the 'escape wheel bridge' number.

Here's the problem with using Ryan's chart (or any chart for that matter):Įvery Speedy Pro has a unique number on the escape wheel bridge.
