Fine and exceptional vintage 34mm ARSA Springmaster Dead Beat seconds steel wristwatch, equipped with rare manual winding Cal. Chezard 7400, made circa 1958s in great almost NOS condition. Beautiful & plain silvered dial with long indices, luminous baton hands, steel case, new blue calf bracelet and unique tru-beat feature.
The dead second (“dead” because the hand rests, lifeless, between steps) also known as seconde morte, sauterelle, seconde sautante, jumping second, tru-beat or true seconds is a complication of mechanical watch in which the seconds hand ticks once a second with discrete jumps between them, like the very best marine chronometers or any cheap quartz watch much later. If you see the watch in action you would think it’s quartz, definitely the most ironic watchmaking complication.
Interesting that in 2001, Panerai introduced “PAM 80” a limited edition of 160 watches that is powered by a re-worked Chézard caliber 7400.
So here we have rare 34mm steel watch with beautiful dial, equipped with Cal. Chezard 7400 with truly one of watchmaking’s “insider complications” — only the nerdiest of the watch nerds can spot one in the wild or care enough to buy one.
Watch is in overall great 9/10 condition, running and ready to wear!
