Some brands hit the market like a tsunami, leaving enthusiast forums abuzz for weeks and months. Others make a splash, only to fade off quickly into a ripple. And then there are others yet who fly unjustifiably under the radar (pardon the mixed metaphor), quietly going about the business of making good watches. After having experienced the Havsornen in the metal, I think Octon is part of the latter.
The Tiefsee is a diver with a strong minimalist vibe. The case comes at 41.5mm in diameter, 48mm lug-to-lug, and 12.3mm in thickness. The lug width is 22mm which might not be as practical as 20mm, but certainly much better than 21mm (I have this weird pet peeve against 21mm lug widths.) The entire case is made of 316L stainless steel, the crystal is of the sapphire variant with anti-reflective coating, and the bezel is made of ceramic. Inside beats the Miyota 821A automatic movement which runs at 21,600 BPH (3Hz) and offers 42 hours of power reserve.
The YEMA Superman was first released in 1963, as a professional-grade dive watch. The now iconic Superman bezel-lock at 3 o’clock was one of the first efforts to address the problem of accidentally disturbing the bezel while diving. Many iterations and later, and we find ourselves looking at the latest release from the brand--the Superman 500.
