Longines produces timepieces with standard functions like the time, date, GMT, or a chronograph — but this new timepiece has a complication that’s a little more interesting than the Saint-Imier-based watchmaker’s usual fare.

The Conquest Heritage Central Power Reserve is presented in a conservatively sized 38 mm x 12.3 mm stainless steel case, that weighs just 69.5 grams on the alligator leather strap.

Like the rest of the Longines Heritage collection, this is a vintage-styled watch — with a modern case, movement, and sapphire crystals front and back.

With a sector dial, adorned with hand-applied faceted indices, and retro hands, the Conquest Heritage Central Power Reserve has an appealing and timeless look, available with either the champagne dial with gilt hands and indices (as shown), a slate gray dial with gilt hands and indices, or a black dial with silver hands and indices.

As the watch moniker suggests, the marquee feature is the central power reserve indicator which uses two discs to show how much of the 72-hour power reserve is remaining. If not being worn the reserve automatically depletes. And if wound or worn, the reserve automatically winds, until it reaches its 72-hour max. The indication is marked numerically up to 64 hours, however, each mark represents 8 hours so the max is the dot positioned counterclockwise one graduation from the 64 numeral.

Swatch Group’s ETA-based caliber L896 (with a power reserve module added on) displays hours, minutes, central seconds, date, and power reserve — it automatically winds (or can be manually wound), beats at 3.5Hz, and has a silicon balance spring. The movement, which is visible through a clear caseback, is machine decorated with perlage on the bridges and stripes on the rotor.

The case takes a 19 mm lug width strap and is water resistant to 50 meters.

Retail is $3,800.
