The Jaeger-LeCoultre Deep Sea Chronograph ref. 2068570 is not only a true example of horological innovation, but a milestone in Jaeger-LeCoultre's history. This is the first time that the historical case of the Memovox houses a three-counter chronograph movement. The stainless steel case on this watch measures 42 mm wide and is water resistant to only 100 meters/330 ft.

The Deep Sea Chronograph is a sophisticated diver's watch that features a 12-hour chronograph and a chronograph-operating indicator. This indicator features a circular aperture located at 12 o'clock right above the central pinion and underneath the Jaeger-LeCoultre logo.

The chronograph-operating indicator is fitted with a disc that changes when the chrono mechanism is engaged, stopped or disengaged. When the chronograph is not running the circular aperture will display a full white circle, half red and half white when the chronograph is running and full red if the chrono has been stopped while running. The chronograph-operating indicator is inspired by the Jaeger-LeCoultre 1930s 'chronoflight' on-board instrument.

The Jaeger-LeCoultre Deep Sea Chronograph features a matte dial with three registers opposed to the two registers on the Deep Sea Vintage Chronograph. Chrono-hours register at 9, chrono-minutes at 3 and running seconds at 6 o'clock. The finish of the dial is extremely matte and very grainy providing the perfect vintage look and feel to this timepiece. The markers on the dial as well as the hands and numbers on the chrono registers are white. The watch is also fitted with a matte and soft to the touch uni-directional rotating bezel that rotates very smoothly and with ultimate precision. Both the bezel —only the dots and the arrow marker at 12 glow— and the dial feature strong and long lasting luminescent material.

The watch comes with a nice thick case with polished and brushed areas, a domed sapphire crystal and old school chrono pump pushers that complete the overall vintage look of this fantastic watch. The case back is solid and is nicely engraved with the iconic diver silhouette as well as other traditional Jaeger-LeCoultre markings including the 1000 Hours Control logo. The watch is powered by the automatic in-house calibre 758 composed of 340 parts with a power-reserve of 65 hours.

To complete the vintage look of this amazing timepiece, the watch is fitted with a tropic leather strap —with perforations and a tang buckle. If you are looking for a comfortable and understated diver's watch, then this is the one. The watch is extremely comfortable and wears exactly as a 42 mm timepiece.
