I have a 1970's Trinity gilt dial must de Cartier quartz and . . .

 

. . . the high capacity (1.60mm thick ) battery last between 4 and 5 years. It remains very accurate after all this time. No seconds hand preserves the power. Who needs a seconds hand on a quartz watch? The 9J movement is by Frederic Piguet cal 820 (Cartier cal 81). I think Cartier treats its general quartz and mechanical movements with equal emphasis or certainly did so, including the similar prices. I think the big query was and remains how long will a quartz movement last against a mechanical movement that can last 100 years + +? The answer may well be the manufacture of the batteries in 100 years time.


Picture below.  Gent's watch very small by today's fashion.
