My 7C43-7010 landed today It is well kept and all original - including signs of use ... just as I like it to be I just noticed an extra number on the caseback - where the "Battery change" text is. It reads: B0412 What does this number tell ?

 

[Pei Der Han]

Pretty sure that is not original.

Could be a stock number of some kind for an issued watch; military or otherwise.

An issued watch of some sort sounds likely, Pete. More info needed

Pete, did You mean that the numbers are not original or that the watch is not original ... ?

Thats interesting - I agree with you and Pete that the number is not original, I hope somebody can shed more light on the extra numbers, and give this watch some providence!


Nice catch BTW!

I have seen those stamps before....speculate that they are for dive school/hire??

Nice example

Yours is not alone..Here's a couple of examples of similar casebacks from pictures I had saved on my hard drive. Not sure of the significance of the numbers. They aren't my pictures but ones that I had saved for one reason or another.
