A different sort of diver.

Compressor-Case Inspired

The original NTH Tropics were inspired by the compressor case diving watches which proliferated from the late '50s to mid '70s - marvels of engineering which established an iconic design language.The Super Compressor watch case was patented in 1956 by Ervin Piquerez SA (EPSA).  They designed a patented case sealing method that actually became more water tight the deeper the watch went. The deeper you went, the more pressure was applied to the case-back, pressing it against the O-ring gasket.These divers were thinner in profile than the mil-sub style models like the Blancpain Fifty Fathoms, and featured two crowns and a timing ring underneath the crystal as opposed to a ratcheting external dive bezel.  Throughout the ‘60s and ‘70s, brands likeJaeger-LeCoultre, Hamilton, Bulova, Enicar, Universal Geneve, and Wittnauer used the EPSA cases to design their own divers, some of which are shown below.  


Like with the NTH Subs, we wanted to recreate - and update - their simple, timeless elegance. Inspired by these compressor cases, each Tropics model shares the same dual-crown, cylindrical case with straight lugs, raised and double-domed anti-reflective sapphire crystal, and a deeply-engraved case back featuring a diving bell in high relief. The Tropics combine the capabilities and toughness of a diving watch with the more discreet profile of a modern dress watch - what we ended up with is a our version of the ‘gentleman’s diver.”

We gave the Tropics 20 ATM water resistance, a fully-lumed internal bezel, faceted lugs, a combination brushed/polished case and an accurate, Miyota 9 series automatic movements. Then we kicked it up a notch with deeply-textured dials, applied indices, and a vintage-style, fully-articulated 5-link bracelet with double-locking diver's clasp. We even threw in a classic, "tropik-style" rubber strap, to complete the vintage look.

The Tropic v.2s

In March we are releasing 2 models with 2 variants:

Antilles Dark Rum

Antilles Cointreau

Azores Absinthe

Azores Blue Curaçao

Never Stop Improving

We were happy with the response to our original Tropics, but we wanted to make sure these models evolved.  The differences between the original Tropics and the v.2s are as follows:

  • Miyota 9 series movements – the 9015 for with-date versions, and the 90S5 for no-date versions. No phantom date changes. 
  • All dials now share a complex “rough-grain” texture and applied indices.
  • Updated tapering bracelet and clasp.  But don’t worry - they’ll also come with a “Tropik-style” premium rubber strap shown below.
