Today, we’ll discuss the new Synchron Military Poseidon Black Edition, the latest release from Rick Marei’s retro-themed brand. In many ways, I think this watch qualifies as the most traditional Military model yet. Plus, with its more typical black dial, it makes for easier reading than past variants. Let’s take a closer look.

Synchron has been a nice little surprise since Rick Marei resurrected the name back in March 2021. Thus far, we’ve been treated to two models that pay tribute to the 1970s Doxa Army. The watches have been fun, limited in nature, and, in my view, an overall treat for the eyes. Before we get to the latest Poseidon Black Edition, let’s take stock of the brand’s first two watches.

Synchron models resurrected thus far

The Synchron brand came on the scene back in March 2021 and kicked things off with the controversial Military Diver model. This was a clear homage to the old Doxa Army, and it did well by selling out its run within hours of its release. Controversy ensued because Rick previously worked for Doxa, and Doxa famously launched a small Instagram counteroffensive. Fun stuff indeed!

The brand returned in January this year with its second limited-edition offering and partnered with Swedish dive-gear maker Poseidon. The Military Poseidon brought a different colorway and handset, along with moving to the La Joux-Perret G10 with 68 hours of power reserve. Once again, the run of 1,000 pieces sold out swiftly.

The Synchron Military Poseidon Black Edition

Today, the Military Poseidon Black Edition shows its face, and I think it’s a logical next step for the brand. Thus far, we’ve had two rather eccentric-looking pieces, and many commented that the first Poseidon model was a tough read with its small hands. The newest watch doesn’t bring in a third set of hands, but they’re far more legible against a black dial.

Synchron Military Poseidon Black Edition

Speaking of the dial, it gives off a very different look from the previous Synchron releases. Notably, we’re used to seeing a black outer ring that runs along and through the printed luminous hour indices. The Poseidon Black Edition, however, contains no such ring. Here, the entire dial is black. Some may miss the segmentation, while others will find this rendition far more traditional and familiar. I had a look at photos of my old Doxa Sub 300T Sharkhunter, and oddly, there’s a much closer resemblance to it than the Military models. That’s not a negative in any way, but it is a change away from the more detailed, ornate dials we’re accustomed to from Synchron.

Dial details

Potential owners of the Poseidon Black Edition will likely be interested in the fact that the dial is glossy instead of matte. I’m glad Synchron made this choice as it gives off a higher-end vibe. Plus, when combined with the 120-click unidirectional dive bezel with sapphire inlay, it gives the watch a very liquid appearance. The watch contains signature yellow elements from Poseidon’s logo, which are replicated on the minute hand and part of the sweep-seconds hand. It all blends well with the white brand logo, minute track, and “Old Radium” Super-LumiNova. The date wheel adds further contrast with its black font and white background.

Other specs

If you’re technically familiar with the prior Synchron releases, then there are no surprises with the latest Poseidon Black Edition. The 316L stainless case retains the shape we all know and generally love. The dimensions are eminently wearable with a diameter of 42mm, a lug-to-lug of 45mm, and a thickness of 14mm. The 20mm lug spacing will fit a host of options, including the supplied black or yellow Tropic rubber strap. The Poseidon-adorned screw-in case back and signed screw-down crown help assure water resistance to 300 meters. As far as the movement, the automatic La Joux-Perret G10 returns, making this watch a nice step up from the usual small-brand fare.

Thoughts on this release

It’s hard for me to find fault with the bulk of Rick’s releases. As a dyed-in-the-wool vintage nut, his watches feel like continuations from a time that has long since passed. Of course, they’re modern and reliable, but they come off as authentic. The new Poseidon Black Edition is no different in that regard. I’ve had the opportunity to wear this piece for a couple of months now, and it’s an easy watch to enjoy. It looks good enough to wear with more than just beach clothing, but it’s also a great accompaniment on a summer trip.

Now, I will admit that the earlier pieces were more funky and unique, but they also received their fair share of criticism due to either polarizing design or readability issues. This newest piece addresses those concerns. I also think that for those who are looking for an easier watch to wear daily, a black-dialed diver is about as easy as it comes. This watch should do well with fans of Rick’s work and even newcomers who like a nicely made retro diver. The co-branding, due to the Doxa profile, is also likely a bonus for most.

Pricing and availability

The Synchron Military Poseidon Black Edition will be made as a limited edition of 1,000 pieces and should begin shipping in October 2023. Pricing will begin at US$990 and increase to US$1,290 after an introductory period (if history is a guide, the watches will not last past the initial period). The pricing, if you’re wondering, is the same as the last Synchron from this past January, so inflation hasn’t reared its ugly head quite yet here. The watches will be sold directly and solely on the Synchron website. Overall, it’s another nice release from a brand that I enjoy following.
