Born for the Battlefield. Built for today.
The FILTHY 13 is the definitive tool watch for those who demand more from their wrist. Inspired by the legendary Dirty Dozen — the 12 watches commissioned by the British Ministry of Defence in WWII — the FILTHY 13 collection is an unapologetic evolution of that storied heritage, engineered for the modern collector.
The 316L surgical-grade stainless steel case delivers the durability and corrosion resistance demanded by serious wearers. The deep black dial brings a crisp, high-contrast legibility that reads instantly in any light — clean, confident, and unmistakably purposeful. Whether you're in the field or the boardroom, this watch commands attention without asking for it.
This is not a dress watch. This is not a fashion piece. This is a tool — precise, purposeful, and made to be worn.
The case
Drilled Lugs
Aside from its tool watch aesthetic, drilled lugs provide a level of functionality to your watch. Strap changes can be done in an instant, without worrying about scratching the underside of your lugs.
Solid Caseback
The Filthy 13 features a solid stainless steel caseback showcasing an embossed TUUL logo at the center, with the watch's specs and highlights engraved along the perimeter.
Bead Blasted Finish
Our watch cases are custom molded from 316L stainless steel, which undergo an intricate bead blasting process. The result is a smooth bead blasted finish with subtle texture.
Swiss Movement
Powering the Filthy 13 is the workhorse that is the Sellita caliber SW261-1. This is a self-winding automatic movement with up to 41 hours of power reserve. The movement has 31 jewels and a frequency of 28,800 vibrations per hour.
The Dial
Railroad track
Our dial features a minute "railroad track" with 60 minute hashes, echoing the original Dirty Dozen watches.
Luminous Indices
Your watch shouldn't have to be visible only during the daytime. We've utilized Swiss Super-LumiNova®️ technology for both the hands and indices to make your watch legible under the darkest conditions.
Sub-Seconds
Just like its Dirty dozen roots, the Filthy 13 boasts a sub-seconds dial at the 6 o'clock position, highlighted by a step-down or recessed dial, beveled edge and "vinyl" swirls.

A Modern Military Classic
Screw-Down Crown
10 ATM WR
It is essential for a tool watch to perform in all conditions, and the Filthy 13 is well equipped to handle the elements. The large 7mm crown has grooves or "teeth" making it easy to grip, and its screw-down function seals your timepiece up to 10 ATM (100 meters) against water infiltration to ensure the safety of its inner workings.
TOUGH PACKAGING
Tactical TUUL Case
Just like your watch, the toolcase it comes in should be both durable and functional. Ours are made from polypropylene and fiberglass, materials low in density and high in heat resistance, making them tough as nails. The case has an IP67 waterproof rating, which means it is protected against water. The interior holds EVA foam to cushion its contents, with custom cutouts to house your watch, warranty card and manual, spring bar tool, as well as an extra slot for an additional strap. The easy to grip rubber handle allows for ease of accessibility, so that your watch can go with you wherever you go.
