Looks good to me, but the proof is in the running of the watch. These can get rather delicate with age from all I've heard.whats your opnion about this vintage electro-mechanical quartz luch watch. never own such a mechanism. is it like bulova acutron with smooth second hand ?
In answer to your other question; no this is not like an Accutron which features a high-frequency tuning-fork as the drive mechanism. This Luch 3055 uses an electromagnetically impulsed, transistor-switched balance-wheel driving the movement through a jewelled pallet-lever and escape wheel, so the second hand beats at 8 per second (28,800bph). Essentially, the base movement is one of the more refined examples of electromechanical movement such as were made by many manufacturers in the 1960s and early 1970s, but with the added feature of a quartz oscillator and microchip to control the switching on the balance. It was an attempt to leverage as much established technology as possible to implement quartz timekeeping, but the result was unfortunately rather complicated.
