SYNCHRON Military Poseidon Ice Diver [from beneath the GREY ICE]

Destined for a different type of cold warfare! 

This is the new Synchron Military Poseidon Ice Diver, a diver’s watch with a storied past, a bone-chilling present and a long and felicitous future on the wrists of the Synchron faithful. 

Making its return just two short years since it disrupted the calm waters of the Swiss retro diver’s watches space, this unapologetic child of the 70s is back again with an icy new look and steely intent.

Because this new Poseidon Edition of the Synchron Military watch now boasts not one but two exceptional co-collaborators; first and foremost of which is the famous Swedish dive-gear manufacturer, Poseidon Diving Systems whose emblem proudly adorns the dial like a black eye on prize-fighter's face. But also the Swedish Armed Forces Diving units who will be real-world testing the watch in the frigid, artic waters that are known to plummet to temperatures as low as -30 ◦C, and whose valuable input contributed to specific design elements of the watch.

These tests will be conducted alongside other military-spec. diving gear, most notably from Poseidon, who is a regular supplier to the Swedish Armed Forces diving units. 

Fittingly, the new Synchron Military Poseidon Ice Diver will make its official debut on the eve of COLD DIVEX 2023 winter demonstration, an invite-only event hosted by the Swedish Armed Forces Diving and Medical Centre in Boden, Northern Sweden.

Showing deference to that rare tool diver, once issued to Swiss combat divers during the 1970s, Synchron makes its return with another Military Limited Edition diver’s model combing the best of modern watchmaking tech, expressed through the flamboyant design language of that same era. And like its predecessor, the 2023 Military Poseidon Limited Edition watch is built around a 42mm tonneau-shaped CNC-machined, 316L marine-grade Stainless steel case that is water-resistant to 300 meters. Its case is topped by domed crystal and a 120-click unidirectional rotational diver’s bezel with a sapphire inlay and featuring a luminous dive-time scale with ten-minute increments and a luminous 12hr marker. Meanwhile, beneath the AR-treated sapphire glass is the inimitable high-contrast ‘Military’ dial with its ecru “Old Radium” colored SuperLuminova, the base of which is a light grey (not the typical snow white that one might expect to see on an “ice diver”) that alludes to the newly formed “grey ice” found floating atop the frozen Nordic sea. Yes, grey-ice is really a thing. But moreover this pale grey which is picked up by the Ice Diver’s barrel-shaped steel case and repeated once again in its ISOfrane strap reflects the stony stares of those specialist operators of the Swedish Armed Forces diving units as they breach said grey-ice. Powering this ice-diving, pale-faced fiend is a La Joux-Perret manufacture automatic movement, a Top Grade Swiss-made caliber using the workhorse ETA 2824 as its base. The G100 caliber has also been adjusted to four positions, and is further enhanced by a solid Tungsten uni-directional oscillator, and is set on ball bearings, is with KIF shock-protection, and has a power-reserve of up to 68 hours from a full wind.

Limited to 1,000 numbered pieces, the Synchron Military Poseidon will be available with a pale grey / off-white dial. Buyers will be able to choose from two handset colors: black or white. 

It has an official retail price of $1,290 USD. However it may be pre-ordered for $990 for a limited time during the launch period with expected delivery during February 2023. ONLY available from synchronusa.com

Thoughts? As I look up to the Nordic sky on a cold winter’s night I am in awe of the Northern Lights with all their swirling waves of light. But beyond the dancing green and purple, the stars have aligned – bringing into play a troupe of elements. 

The Swiss Army heritage as seen in the dial, the iconic dive-gear manufacturer and of course the (soon to be part of the World’s greatest defense alliance aka NATO) Swedish Armed Forces diving units. 

That’s why I would gladly crawl over broken glass just to lick the wrist of one of those guys that were lucky enough to test one. 

But what do you think? Don’t think too hard or too long, the last batch of these SOLD OUT in under 24hrs!


  1. Looks better on the black strap as seen on the website. Would love it is the minute hand was black too.
