The Longines HydroConquest gets two new green looks for 2020!

You might remember the HydroConquest ALL-BLACK Ceramic ZrO2 from last year with its case made entirely from black ceramic.

Longines’ sport-diver family is now available in two shades of green. These models will join the aforementioned All-Black model as well as; black blue and grey variants.

There is the HydroConquest Green ref. L3.781.4.06.9. with its subtle matte Khaki green dial as well as a variant that has a matching green ceramic bezel, as advertised by the “ZrO2” on its dial.

The new green models come on either; Stainless steel link bracelets with a double security folding clasp with integrated diving extension, or green rubber diver’s straps in matching green.

At first glance the HydroConquest Green models are quite hard to tell apart but on closer inspection, you’ll notice that one model’s dial has a bright green vertically brushed pattern.

This version’s dial and bezel inlay are made from ceramic; hence the ZrO2 text on its dial.

The watches are also available in two sizes – choose from 41 or 43mm in diameter, 300 meter water-resistant cases.

Both case sizes house the same movement, a self-winding mechanical Longines L888.3 caliber with an Si balance spring, beating at 25’200 vibrations per hour and providing 64hrs of power-reserve.

In addition to the HydroConquest’s 30bar depth rating, it also has: a unidirectional diver’s bezel, a screw-down crown and case-back and an AR-treated Sapphire crystal.

The crown is safely nestled in the middle of an integrated crown guard while the case-back proudly sports an historic winged Longines logo.

The 41mm variant comes with an interchangeable Stainless steel bracelet and a green rubber strap in the same shade as its dial.

No tools are required as the HydroConquest makes use of Longines’ easy change system.

The Longines HydroConquest Green ref. L3.781.4.06.9 has an MSRP of 1’390€.

Thoughts? It would seem that the industry can’t get enough of green at the moment. It’s such a great color for a diver if done right i.e. muted matte khaki or olive hues.

Here’s my absolute favorite green diver, Panerai’s Submersible VERDE MILITARE. BTW which of these HydroConquest Green models would you go for?



  1. Very nice watch at fair price considering Longines is an entry-level to the luxury segment.

  2. The 41mm variant comes with an interchangeable Stainless steel bracelet and a green rubber strap in the same shade as its dial. <= this is fantastic selling point, i will see if i can acquire this soon at Longines or The Swatch Group.
