I’ve replaced the band once (friction pins) and the battery several times. I have to remember the back is not a pry open, but a twist. Large needle nose did a good job, firmly seating the tips in opposing notches. Battery = 395 / 399. $7 at Walgreen’s. Won’t do that again. Amazon.
I noticed that some versions of this model have a 23 and 13 flanking the Swiss Army at 11 and 1.
Cleaning up some basement boxes, I found this pocketwatch that I recall Barbadee giving me when I was young. I would carry the watch around and use it sometimes.
I wound it up, and it is ticking and keeping time, here some 99 years later from the 1915 inscription.
The watchmaker is Rode Watch Co. You can see the F/S adjustment. It is set a bit to the slow side. There is a “Swiss” stamp on the edge of the mechanicals (not pictured.) The back interior case reads:
To the right of Illinois is a smaller number: 734301 (from what I can tell.)
At the bottom there appears to be a mark of some kind like a signature.
