1957 Bulova Wrist Alarm
Stainless Steel case, top and bottom access, date stamped L7, dual Bulova signed crowns - top crown winds and sets time / bottom crown sets and activates alarm. Looks to be an original dial, luminous hands and markers, alarm hand with red arrow. Functioning Swiss 11AERC manual wind movement dated L7. Caseback does have a serial number, located to the left of the small rivet holding the interior post that works with the alarm feature.
Quite an interesting watch, a bit more complicated to take apart (& re-assemble) than the usual watch. No Wrist Alarm ads for this one have been found to date, but we already have three late 50s examples in the database and 'Wrist Alarm' is a proper model name as indicated in the '55 and '58 pricelists.
