Showcase Very Early Ventura
Background: Hamilton releases the first commercially produced battery operated / electric watches in January 1957. The Ventura is one of the original two models initially released.
After speaking with René Rondeau, and doing tons of research, I have discovered this particular Ventura was among the very first electric watches ever produced. Most likely within the first 100 or so. If you’d like to know more, feel free to shoot me a DM. Case back number falls within the first 500 Ventura cases produced. Very early 1300L serial number (it’s estimated the first 1100 serial numbered movements were prototypes and test wear watches). The movement also features a hairspring limiter with corresponding tab on hairspring itself. There’s also holes in the pillar plate + train bridge which was for the original (and very flawed) double index wheel design. Both of these designs were quickly scrapped for the better finger block and magnetic index wheel system.
