The Torsk-Diver Pro GMT 39

Delivery: Late August 2026 

Early Preorder Special:

Use code TORSKDIVERGMT for $25 Off 

Inspired by the legendary USS Torsk (SS-423) submarine docked in Baltimore’s Inner Harbor, the Torsk-Diver Pro GMT 39 is built for those who navigate both land and sea. 

Almost identical to the original Torsk-Diver Pro (43mm) but in a smaller size, a GMT movement, and an updated micro adjustment clasp.  

Its 39mm 316L stainless steel case houses the Miyota 9075 True GMT automatic movement, allowing precise tracking across time zones. A domed sapphire crystal with anti-reflective coating, Swiss Super-LumiNova X1 lume, and 200m water resistance ensure clarity and reliability under any condition.

Each dial is made using a multi stamping process to create textured sunburst.  The micro-adjustable bracelet clasp and see-through caseback complete a design that honors exploration, craftsmanship, and Baltimore’s maritime heritage.

What's Included:

Torsk-Diver Pro GMT 39 Timepiece

Extra Strap - Brown Leather (20mm)

Ellie ★★★★★

The preorder process was smooth and the $25 off code applied without any hassle. I'm already picturing the submarine-inspired design on my wrist, and the 39mm size should sit perfectly under a dress shirt cuff. Counting down the days to that late August arrival.

Hannah ★★★★★

The wait until late August 2026 feels painfully long, but that $25 early-bird code made the preorder sting a bit less. I’ve been eyeing a 39mm GMT for months and the Onyx Black dial looks even sharper in person than the product shots suggested.

Natalie ★★★★★

This GMT is my first dive watch purchase, and the 39mm Onyx Black case is the perfect middle ground between bold and wearable. Counting down the days to that late August delivery—the $25 preorder code made locking in a submarine-inspired piece feel like a no-brainer.
