If you’re in the market for an affordable dive watch, especially if you’re looking at microbrands, then you’re almost exclusively limited to watches inspired by vintage divers from the mid-twentieth century.
It’s easy to understand why that is. Modern dive watches were invented in the 1950s, with icons like the Blancpain Fifty Fathoms, Rolex Submariner and Omega Seamaster 300 all debuting that decade.
The 1960s and ’70s then saw the explosion of military-issued dive watches, along with more adventurous designs such as Super-Compressors and colorful decompression timers. I love mid-century dive watches as much as the next guy, but sometimes, I’m in the mood for something fresh and different.
If you’re like me, then allow me to introduce you to the Peren Regia Lunar Eclipse Dark.

Going Dark
Peren is an independent Swiss brand whose watches carry the Swiss-Made designation and which also boast some niceties like in-house assembly and regulation, and some hand-finishing on the cases.
The brand’s latest offering, the aforementioned Regia Lunar Eclipse Dark, is packed to the brim with the kinds of specs I’ve come to expect from a microbrand diver in 2025: an AR-coated sapphire crystal, Sellita SW200 automatic movement, BGW9 Super-LumiNova, 200m water resistant with a screw-down crown … you know the drill.
