rare fanion oversize trench watch for repair
steel case with flip open back ,this is not a pocket watch conversion ,wire lugs have been there forever and theres no top ring
large oversize at 40mm
worn on the inside of the wrist it could be easily read as a driver or pilot.
porcelain dial is clean and crack free ,oversize arabic numbers with red 12
movement is signed fanion , balance swings ,crown is tight .
it clicks out but does not adjust.
for repair or spares ,but no doubt quite rare from the early wrist watch period
can post at cost
