Baltic rates it to 200 m (20 ATM). Its twin-crown layout evokes classic compressor divers, but the available product specifications do not establish that it uses the historic pressure-activated case-sealing system associated with “super-compressor” watches.
What the two crowns control
The crown at 2 o’clock turns the internal bezel beneath the crystal. Baltic describes the bezel as bidirectional and says the crown is not screwed onto the case, allowing adjustment while preserving the manufacturer’s stated water-resistance rating. The bezel tracks up to 60 minutes; its position under the crystal also shields it from impacts and reduces the chance of inadvertent operation.
The crown at 4 o’clock winds the automatic movement and sets the time. This separation is the practical reason for the Dual-Crown name: one control operates the timing scale, the other the watch itself.
Compressor-style design versus a super-compressor case
The Aquascaphe’s twin crowns and internal bezel resemble the layout commonly called compressor-style. Baltic describes the watch as a compressor-type case, and Hodinkee introduced it in 2021 as a “super-compressor-style evolution” of the Aquascaphe. Hodinkee also explains that “super-compressor” historically refers to a patented case-sealing method developed in the 1960s, although the term is often used more loosely for watches with two crowns and an internal bezel.

Those meanings should not be conflated. A similar appearance or bezel control does not prove that a watch uses the historical pressure-activated sealing construction. Baltic’s published specifications establish a 200 m (20 ATM) rating, but do not identify that specific sealing mechanism. Fratello reviewer Lex Stolk called it “every inch a compressor”; that is his design characterization, not certification of the case’s sealing technology.
Case dimensions, movement and dial
| Specification | Baltic’s published details |
|---|---|
| Case | 316L stainless steel |
| Diameter | 39 mm |
| Lug-to-lug | 47 mm |
| Thickness | 11.9 mm overall; 10 mm without the crystal |
| Lug width | 20 mm |
| Crystal | Single-domed sapphire with internal anti-reflective coating |
| Movement | Automatic Miyota 9039, with stop seconds and a 42-hour power reserve |
| Dial | No date; blue sunray or glossy black; BGW9 lume |
| Water resistance | 200 m (20 ATM), as stated by Baltic |
These are manufacturer specifications on Baltic’s product page, accessed in 2026. The 39 mm diameter is only one part of fit: the 47 mm lug-to-lug span, thickness, wrist shape and strap all affect how the watch wears. Fratello’s reviewer found the rubber strap comfortable, an individual impression rather than a universal fit assessment.

Strap choices and everyday use
Baltic lists rubber sport (FKM) and steel Beads of Rice or Flat Link straps, and says its straps are compatible with the watch. The 20 mm lug width gives a useful reference when considering other straps, but compatibility should be checked for the exact strap and attachment hardware. For a diver-style watch, the internal bezel offers elapsed-time tracking without an exposed rotating bezel; whether its markings are easy to read in a given setting depends on the wearer and conditions.
The stated depth rating is not a substitute for safe diving practice or confirmation that an individual watch remains properly sealed. A watch’s condition and service history matter when relying on water resistance.

What the launch-era price and history tell you
Hodinkee published its introduction on April 14, 2021. Fratello reported that preorder opened that day at €550 for 20 days, with the price then set to rise to €650 and delivery expected in September 2021. Those figures describe the launch, not the watch’s current price or availability; check Baltic’s live listing for current variants, stock and terms.
Fratello’s 2021 account also reported Baltic’s then-disclosed production arrangement: case-housing parts and movements from specialist manufacturers in Hong Kong, straps sourced and made in France, and assembly and adjustment at the brand’s atelier in Besançon, France. That is dated reporting and should not be assumed to describe Baltic’s current sourcing.
