Every U-Boat timepiece is individually handcrafted in Italy by master watchmakers, dedicated to the highest level of precision engineering and finishing, where care and attention to detail are evident throughout the entire process. From the manufacturing to the final assembly of the watch. The U-Boat Doppiotempo 46 Bronzo Green Ref. U-9088 is the latest offering with its unique bronze case and its latest GMT function.

The U-Boat Doppiotempo 46 Bronzo Green Ref. U-9088 features a Swiss Made GMT automatic movement. This 26 jewels ETA/Sellita movement is highly personalized to U-Boat specifications. It allows a 24 hours sub-dial display at 4 o'clock, in tandem a GMT hand that can be adjusted for second timezone. The watch ticks at 28800BPH (4 Hertz) with a power reserve of 44 hours. And the time and date adjustments are made through the "destro" crown at the left side of the case, keeping with the U-Boat’s unique canteen cap, covering over the screw-down crown.

The 46mm full bronze case has a water-resistant of 100 meters, ready to be brought for adventure. The all-new full bronze, bi-directional 24-hour bezel seamlessly complements the bronze case while offering a lockable system with a lever on the right side of the case. It's bold look thanks to the height of 16.5mm and 51mm lug to lug distance - a sizing that exemplifies the main appeal of what U-Boat watches are all about.

As mentioned earlier, the trademark-protected special protective device at 9 o'clock is unique and eye-catching. Reminiscence of the old-school canteen bottle cap, the protective cap makes it an instant statement on the wrist. Notably, on the other side is engraved with the "U-boat" name on its bronze lever. Topping things off, a high-quality scratch-resistant flat sapphire crystal with anti-reflective coating underneath.

Sitting within, the iconic numeral and baton hour markers are done so in a luminous beige tone, treated with SuperLuminova on its superimposed green dial. A matching date display blends nicely on the left side, and the unique 24 hours sub-dial balance off on the right. The handset is a typical U-Boat style, initially found on the Classico model. It is being used here in this new Sommerso collection, while the only difference is the contrasting red hour hand for the 24-hour display. Another signature touch would be to have a visible ruby sitting at 6 o'clock.

Flipping the watch over is a unique patterned case-back in bronze material, secured firmly by 7 screws at the periphery. The design reminds one of a watertight hatch found in submarines, and a quirky “U” opening is made out of fumé sapphire glass right  in the center. With that, the whole U-Boat is genuinely a full bronze sports watch.


SuperLuminova glows in the dark

The U-Boat comes with a 22mm vintage-themed green leather strap with the Maison's logo. Laser-cut strap handmade from hand-finished calf leather and processed according to traditional artisan techniques gives the strap a naturally rugged look and feel, deep green color. Strapping the watch on is through a bronze tang buckle with special antiqued anti-corrosion treatment.



Overall, the U-Boat Doppiotempo 46 Bronzo Green Ref. U-9088 is a premium addition to the new collection, bringing a stunning new GMT function for frequent travellers. This timepiece has won me over with its vintage design and superior U-boat styled case; One can't get enough of it. This exquisite GMT watch presents a compelling set of specs, and as quantities aren't limited, it is less difficult to get in on the action.
