Hanhart doesn’t get talked about nearly enough, so here’s a quick backstory: they’re a German brand out of Gütenbach in the Black Forest, they put the first single-button chronograph into series production back in 1938, and a year later they built pilot’s chronographs for the German Air Force. That red pusher button is still on their watches today.
That’s a real, foundational place in watchmaking history; it’s the kind of lore that other brands build entire marketing campaigns around. Somehow, Hanhart still flies under most people’s radar, but their new Aquasphere Matte Black is an argument that folks should be paying attention.
The 42mm stainless steel case has a fluted black bezel with a ceramic insert and a red marker. The bezel rotates counterclockwise only, which is actually a pretty galaxy-brain safety feature: if you accidentally bump the bezel, it’ll only ever read a longer dive time, never a shorter one.
The dial is matte black, with a silver-coloured rehaut (that’s the inner rim, fyi) and a red-tipped seconds hand. Hands, indices, and the bezel numerals are all coated in Super-LumiNova C1 GL X2 for visibility in low light or underwater.
Water resistance sits at 30 bar (30 ATM) and — because they’re not messing around — the watch carries a helium escape valve, which lets trapped helium gas release safely during decompression after time spent in a pressure chamber or on a saturation dive.
Depending on the production run, the movement will either be a Sellita SW 200-1 or a Soprod P024; they’re both Swiss-made automatics running at 28,800 vibrations per hour with hacking seconds and >38 hours of power.
A high standard
Hanhart’s own rate accuracy tolerance is 0 to +8 seconds a day, averaged across six positions, with no negative deviation in the main positions. That’s a tighter, more demanding standard than a lot of other watches wear as a badge of honor.
It also tracks with how Hanhart has approached its comeback in dive watches generally: no flashy branding push, just genuinely competitive specs — a helium escape valve, three strap options, and Swiss-made movements — on a watch most guys have never heard of.
Where to buy it
The Aquasphere Matte Black is available now in the US through WatchBuys, Hanhart’s exclusive North American distributor, priced at $1,870 on the Hook Strap, $2,060 on the rubber strap, and $2,170 on the steel bracelet.
