The new Zenith Chronomaster Solo Sport could make big waves in the saturated dive watch segment

Zach Blass

Zenith disrupted the chronograph segment with the Chronomaster Sport; today it’s making waves in the dive watch segment with the new Zenith Chronomaster Solo Sport Collection. The question is: is it just another drop in the water of a saturated segment or a cannonball splash that will make everyone take notice? Let’s get into it.

The case

Four models are launching this new line, three of which we have in hand. All are housed in stainless steel cases that are 200 metres water-resistant with a screw-down crown. I won’t speak for any subjects beyond watchmaking, but in terms of watch buying, size irrefutably matters – a make-or-break metric for how alluring a design will be for buyers around the world.

The Zenith Chronomaster Solo Sport is presented in a 40mm case, no cause for concern there – a fan-favourite diameter. Lug-to-lug across the wrist, we have a 46mm measurement, which is great on paper, compact enough for smaller wrists but not too small for larger wrists. However, the fixed bracelet endlinks will net a larger effective lug-to-lug span, though the camber of the endlinks results in more of a wrap around the wrist rather than winging out past the wrist. The lug width of the case is 20mm, ripe to play strap monster with, but there is a reason you will want to leave this watch on the bracelet if you can – which we’ll explore in a bit.

Lastly, case thickness – the measurement that has become arguably the most scrutinised in watch design. I see everyone in the comments, and I am certainly on the record stating that case thickness can make the difference between a good watch and a great watch. The Chronomaster Solo Sport case clocks in at 11.93mm thick excluding the crystal and 13.13mm including the crystal. In my view, that leaves very little to complain about and offers a respectably slender diver for your consideration.

The dials

Unlike the Chronomaster Sport, the Chronomaster Solo Sport has a ceramic bezel insert rather than a full ceramic bezel. The bezel inserts, with a full 60-minute timing scale, match or pair with the dial options, with a black ceramic bezel for the black and white dial configurations and a brown ceramic bezel to match the brown dial model.

The dials are crafted in ceramic, polished for the black and brown dials and sunray-finished for the white dial. This would normally net a more polished, elegant look that has a bit of contrast to the more utility-driven purpose we associate with a dive watch design. But Zenith has added texture to these dials, specifically a Zenith-exclusive high-frequency pattern built around a 45-degree Z motif that adds a sense of grit. You also have a small nod to historical Zenith references, with a shark tooth minute track that adds further distinction to the dials.

The three central hands and applied hour indices are all filled with Super-LumiNova for visibility in darkness, and all the colours have a date window at the non-contentious 3 o’clock position that blends well into the dial. However, the black dial has the distinction of being offered in both date and no-date configurations to ensure there is something on the table for purists out there.

The movement

As the high-frequency pattern on the dial suggests, what really sets this diver apart from the herd is the fact that it is driven by a high-beat automatic movement – which you can see through the exhibition caseback. The in-house El Primero 3620 within is not traditionally decorated. Instead, you have a mix of brushed and grained surfaces within thin bevelled edges for a more modern look. It’s a 60-hour movement, and notably the same movement you would find in Zenith’s marquee Defy Skyline lineup, but the central seconds hand, at 36,000 vibrations per hour, makes a full revolution around the dial in a standard 60 seconds rather than once every 10 seconds as it does on the Skyline. That is something I am very glad to see.

The bracelet

I imagine rubber straps are a feasible future possibility, but as of right now the three colour options are strictly offered on a mixed-finished three-link stainless steel bracelet.

The clasp of the bracelet notably includes Zenith’s ZENCLASP, the brand’s own micro-adjust system that affords you the ability to fine-tune the sizing of the bracelet on your wrist on-the-fly in four increments of 2.5mm with 10mm of total adjustment. This is not your run-of-the-mill micro-adjust.

Presented at Watches and Wonders 2026, ZENCLASP is the fruit of three years of development and is comprised of 41 components, including 10 ceramic balls that secure the locking and positioning functions of the micro-adjust mechanism. To ensure its robustness, Zenith stress-tested the design with real-life testing equivalent to more than 10 years of use or 600,000 cumulative opening and closing cycles. So, yeah, it’s a tough, proven, well-built system.

The verdict

Whereas the Chronomaster Sport launch, rightfully or wrongfully, drew immediate comparisons, the Chronomaster Solo Sport, in my view, brings irrefutable distinction both within and beyond Zenith’s catalogue. In terms of high-beat dive watches, there are only 3 brands that immediately come to mind – two of them owned by the same parent company and the third being Zenith. So having a high-beat El Primero-driven diver is truly a point of difference.

Within Zenith’s catalogue, up until this point, the dive watches we have had from the brand in recent years were within the Defy family – less conventional in aesthetic. So, the Chronomaster Solo Sport presents a Zenith Diver with a more traditional or common expression, yet layered with elements of distinction like the dial motif, ZENCLASP, and, of course, a high-beat El Primero movement.

At US$9,800 for the no-date model and US$10,900 for the date models, I would say the pricing is fair in today’s market. No watchmaker today can really escape receiving comments about watches being priced high, but I think the premium nature of the product, its legend-derived high-beat movement, and ZENCLASP make it a very compelling and competitive offer at its price positioning.
