Unconventional. Dedicated. Unapologetic.


Engineered from 316L stainless steel in Switzerland, this case features a stainless steel finish and twin screw-down crowns. A watch built for travel, it’s water resistant to depths of 150m.


Modern retro visuals meet a bold black and yellow colour scheme. Equipped with a 24-hour chapter ring and internal bezel, this chronometer allows you to read three timezones simultaneously.


Every detail matters. Engineered on both the top and underside, our double domed sapphire crystal offers absolute clarity of the dial from all angles. Its signature convex shape pays homage to the dress watches of the ‘40s and ‘50s – our modern take on retro design.


An exhibition caseback displays the precision engineering within. Because if you've got a Swiss-made automatic movement inside your watch, flaunt it.


As a watch with GMT capabilities, skeletonised hands complement the aviation theme. Wherever in the world your adventure takes you, you’ll always be on time.


A movement that powers a fourth GMT hand around the dial, the Sellita SW330 is one of the most popular dual-time movements available today. It’s been chronometer-certified by COSC, giving it a world-class daily accuracy rate of +99.994%.


Each TRIBUS arrives with a COSC certificate in its own luxury presentation box, piano finished with a push button for easy access. An accompanying warranty card allows you to register your watch and view your online instruction manual. We believe you don’t need to hack down half the Amazon for a physical manual when you can easily download one.


The original GMT watches emerged during the 1950s, part of a jet-setting era that opened a whole new world of exotic destinations. The GMT 3 Timezone COSC is born of the spirit of that time, with a modern-retro aesthetic influenced by vintage aviation watches. Distinctive looks and vivid yellow detailing are all enhancements to a classic.

The TRI-02’s case is crafted from stainless steel in Switzerland, its sleek shape a striking example of the nation’s engineering capabilities. Yet it’s what you’ll see through its exhibition caseback that makes this watch possible. A Sellita SW330 movement powers a fourth GMT hand, read against an inner 24-hour ring so its user can track a second timezone; an outer 24-hour bezel can be adjusted by the TRI-02’s upper crown to set and follow a third.

Each SW330 movement found inside the TRI-02 has also has also passed through the Contrôle Officiel Suisse des Chronomètres, having been tested in a variety of positions and temperatures to guarantee optimum performance throughout. The result: guaranteed accuracy within -4/+6 seconds per day, placing the TRI-02 in the top 6% for all Swiss-made watches.

Nice GMT/ TR1-02 watch

Nice watch with good specs and some colour on the face makes it stand out from my other watches and even with a 50mm lug to lug and male endlinks it still seems to hug the shape of your wrist and fits great also helps with loads of adjustment on the bracelet to help fitment. One improvement though it would be great with some lume on the indices and hands.

Nice as ice at twice the price.

Very nice watch. Dig the retro color scheme. Super smooth lines. Feels great in the hand and on the wrist. The bracelet is fabulous: on the fly ratcheting micro adjust system, plus a choice of two holes for getting an absolutely perfect custom fit. (Haven’t seen this mentioned in reviews.) but it also looks rad on a nato with some yellow. The movement is very nice. Lume would be better, I agree, but I don’t sleep with watches on so it doesn’t bother me. (Personally, I’d also prefer a date.) All in all, the Exceptional fit and finish make this Tribus feel like it’s a smooth cut above other microbrands and up there with watches twice as expensive. Very happy to add this subtle yet stylin’ piece lto the collection!

TRI02 and TRI01

I recently received the TRI02 and the TRI01 in Salmon. I was keen to try out the brand using the recent promotion. I have no issues with the TRI02 (in fact I would likely order another - I like how it wears as well as the design) but on the TRI01 there is a blemish on the number 9 - it looks like a black line cutting into the 9 - which is irritating. I'm not keen on the bulky clasp. O/w the quality seems good.

High quality and finishing watch for all occasions. No regrets!

The movement is running with excellent accuracy. Great clarity on dial. I would have prefer lume on the indices and hands but I can forgive that. Overall a very comfortable watch to wear. A daily wear for me.

Build quality is very good but why no lume?

I like the bold colours of the TRI-02, the two-crown configuration at 2 & 3 is unusual & interesting, though the screw down feature on the upper crown is unnecessary. The size is right at 41mm, the bracelet solid & well engineered with a quick adjust clasp (but no quick release sadly). The deliciously large white numerals are begging for a big dollop of lume, but curiously none at all. Not on the numerals, hands, nor anywhere else. One star deducted for this reason but overall well executed and attractive.
