Today we have a brand new Jaeger-LeCoultre diving watch. It's called the Deep Sea Chronograph, and it is the modern extension of the Deep Sea line, of which, up until today, we've only seen vintage variations - the Deep Sea Alarm tribute of 2011 and the Deep Sea Vintage Chronograph.
It is with this new, three register, 42mm automatic chronograph that we see the Deep Sea line will not be for tributes only, but will encompass the entire JLC sport watch family. Yes, this watch resembles the Deep Sea Vintage chronograph, but ultimately, this watch is very modern (we show you the two side by side, below). It features sapphire glass, a rotating bezel, no faux-aged lume, and water resistance to 10 bar. It's larger than the vintage guys by about 1.5mm, and complies with all the criteria imposed on diver’s watches by the ISO 6425 standard.
Inside this new chrono is the JLC caliber 758 featuring with a 65-hour power reserve. But, perhaps the most noticeable trait of this new JLC Deep Sea Chronograph is the activation aperture that sites below 12 o'clock. This display allows the wearer to know, without a doubt, if the chronograph is running, stopped, or ready to be used. This is how it works:
