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.


Polished lugs with brushed profile just make it look like its brother A.Lange & Söhne, but it prices lower.DSC00739

The finishing of its caseback is just attractive. From outside to inside it’s polished, matte, and then brushed. Different surface has different property of reflections. Under light it comes alive.DSC00747

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.DSC00733

From my macro lens, I saw the first time Jaeger-LeCoutlre’s three-hand model has that kind of high-level finished hands. Beveled edge and matte side hides all vestige of raw processing.DSC00737

Luminous dots are well painted. They are amazingly uniform and the edges of lum-dots are all very sharp and smooth.DSC00738

Hour marks and date aperture are nicely done. Shiny and sharp, it makes a contrast with the silver matte dial.DSC00735

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. DSC00748

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.DSC00741

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.DSC00746
