Following the launch of new ceramic bezel-equipped HydroConquest Dive watches by Longines in 2020, they’ve announced six two-tone versions for 2021.

All of the new two-tone references being added to the catalog come in a 41 mm diameter stainless steel case. Longines also makes a 43 mm HydroConquest but that size was not included in this announcement.

Three of the references of the HydroConquest Two-Tone Dive Watches come in either green, black, or blue sunburst dials, with matching ceramic inserts, and yellow gold PVD plated bezel, hands, and hour markers. While the other three come in either gray, black, blue sunburst dials, with matching ceramic bezel inserts, and rose gold PVD plated bezel, hands, and hour markers.

As with the HydroConquest models launched last year, these are 300 meters water-resistant, have screw-locked casebacks, screw-locked crowns, and sapphire crystals. An ETA A31.L02 (caliber L888.5) powers the hours, minutes, center seconds, and date. The 3.5Hz, 21-jewel automatic movement has a maximum power reserve of 72-hours and features an anti-magnetic silicon balance-spring that extends the service intervals and improves chronometry.

The 2021 HydroConquest Two-Tone Dive Watches come with either a two-tone steel bracelet or a textured rubber strap and retail for approximately $1,600.
