Does anyone know what an outer chapter ring marked in increments of 25 means please? Meaning 1 is marked 25 and 12 is marked 300. The sub dial is marked 1-29 and there doesnt appear to be a centre seconds pinion/hand on this 1909 pocket watch

Is this a gunner/howitzer's rangefinder watch?

A photo would be nice. Could be lots of things. The rate at which the hands move, especially if not in normal minutes/seconds, would help too.

Need pictures.

might be for film but the 1-29 subdial would be wrong.

Very hard to answer without more info. How fast does the hand move? And why are there 1 through 12 markers on a stop watch? 😕

There are "high beat" 1/100th second stopwatches with unusual scales and a 300 at 12, but these date the 1950s:

Well that one is a chronograph, not a stop watch, so the 1 through 12 markers make sense.
c
Sorry, i meant that this seemed to be governed by the stop watch function, not that this chrono was actually a stop watch. That is the dial which is being described to me. Increments of 25, from 25 to 300. Sub dial has that half minute range as on MRC's picture of the George Stockwell. But the watch being described to me may well (in view of that photo) have lost its centre seconds pinion? - as well of course as its centre seconds hand!
