The Baltic Hermétique Tourer Bronze is a compact, vintage-styled everyday watch with a bronze case, three fumé dial options and a Miyota automatic movement. Time+Tide Watches reported a 37 mm case, 150 metres of water resistance and a color-matched FKM rubber strap in its 6 December 2024 introduction. It is not presented as a dedicated dive watch.
What is the Hermétique Tourer Bronze?
Baltic’s Hermétique Tourer Bronze pairs a CuAl8 bronze case with a dial in blue, green or brown. Time+Tide Watches described the design as vintage-inspired, with brushed lugs and a polished bezel. Its bronze case is expected to develop patina as it is worn; the resulting appearance can vary with skin chemistry and wear habits.
The article’s author, Buffy Acacia, called it “what you may have been waiting for if you don’t yet own a bronze watch.” That is an editorial opinion, rather than a manufacturer’s claim.
Case, dimensions and water resistance
Time+Tide Watches lists a 37 mm case diameter and 46 mm lug-to-lug measurement. Thickness is 10.8 mm including the domed sapphire crystal, or 8.3 mm excluding the crystal. The sapphire is reported to have an anti-reflective coating.

#1 Best Overall
- Total Bronze: This timepiece features an exceptional bronze case, buckle, and crown—all solid bronze. Natural oxidation due to environmental factors means stains and patina changes are expected upon receipt and over time,which is normal
- Material: CUSN8 bronze case crown buckle,total bronze watch, synthetic sapphire crystal,genuine suede leather band
- Movement: Japan NH35A automatic movement, 24 jewels, 41 hours of energy storage
- Luminous: Swiss Super bright luminous backlight, excellent night brightness
- Waterproof: Water resistance up to 20 ATM / 200 meters / 656 feet
The stated water-resistance rating is 150 metres. The same article distinguishes the watch from a dive watch while saying the rating can accommodate swimming. Its FKM rubber strap is also described as suitable for swimming and hot climates. These details do not make the model a dedicated dive instrument.
Dial colors, lume and strap
The three listed variants are blue, green and brown fumé, each paired with a coordinating Tropic-style FKM rubber strap. Time+Tide Watches reports blue luminescence on the blue-dial version and green luminescence on the green and brown versions; it does not provide comparative legibility testing.
The lugs are 20 mm wide and drilled, which can make strap changes easier. If considering 20 mm watch straps, check the strap’s fit and buckle dimensions as well as whether its material suits your use. The article mentions leather as an alternative some owners might prefer, but does not establish a particular replacement strap as an included option.
Movement and reported specifications
According to Time+Tide Watches’ 2024 article, the watch uses a Miyota 9039 automatic movement displaying hours, minutes and seconds. The article reports a 42-hour power reserve, 4 Hz frequency, 3.9 mm movement height and factory accuracy rating of −10/+30 seconds per day. The accuracy figure is the stated factory rating, not a result from an independent test of this watch.

- Bronze changes with wear. Patina is part of the material’s appeal, but its appearance is not uniform or fully predictable.
- The crown is recessed. Time+Tide’s author observed that it may be tricky to grip; that is a design observation, not a universal experience.
- Choose by dial and lume preference. The established distinctions are the three colors and the reported blue-versus-green lume. No comparative visibility test is available.
- Check strap compatibility. The 20 mm width and drilled lugs support strap changes, but confirm replacement strap fit and buckle dimensions.
