"Aviation" 5 Jewel 29mm Boy's/Gent's Manual Winding Watch

All the way from sunny Croydon - Surrey's watchmaking quarter - The Aviation Watch Company was actually part of Services, one of Britains major watch brands - Made for Services by Louis Newmark and Co this is the final generation of the Newmark movement now with five jewels - The Swiss must surely have been worried?
This little 29mm watch would have been sold for Gentlemen, or for boys, it would not have seemed small in the mid fofties when it was made - Excellent brass case, a lovely slightly aged dial, with sub seconds, and outer journal, The watch runs well, and to time.
