IMHO, Jaeger-LeCoultre Geophysics series is the No.1 three-hand watch of this year. In terms of its price, its details, and its jumping second.
The dial has a quite modern looking, is not vintage at all and has very little relationship with the original Geophysics. It’s very normal from this distance. However, when we have a closer observation, it’s absolutely desirable.
Jaeger-LeCoultre named the jumping second movements as “True second” Cal.770/772. It achieves that quartz motion by releasing a sub-spring constantly. The trigger parts that releases the spring in the 770/772 movements are basically the same as the jumping second system in the pocket watch era. At that time, this system was called “independent second”. This trigger system is far more durable than the 60s Chezard jumping second movement (for example Chezard 7400) so I will not worry about its lifespan.
770/772 movements equip a Jaeger-LeCoultre in-house balance wheel. It’s not so difficult to make such a non-circle balance wheel as all balance wheels are made by CNC machine. And also, its non-circle shape makes no different for the circles when you use it in reality anyway. But, special design is always more attractive than normal design, especially when you don’t need to pay extra.
Stainless steel version uses double deployant clasp and 18k gold version uses pin buckle. I prefer the deployant clasp as it has a very solid, three-dimensional logo on the clasp. This gives some sense of vintage. The logo on the pin buckle is just too flat.
