Glacier Blue Streamliner Urban Auto Watch 23640.S.T.25

The Watch

Briston is a French brand that has been making waves for years with its sport-chic watches built for effortless everyday style. Known for their cellulose acetate construction and distinctly British character, Briston pieces stand out in any crowd. From the Streamliner collection comes this handsome watch housed in a barrel-shaped case. Measuring 40 mm in diameter, with a dial opening of 31.50 mm and a thickness of 12.80 mm, it sits perfectly on men's wrists of all sizes. Crafted from stainless steel and cellulose acetate, it features a screw-secured bezel with a brushed surface finish and mirror-polished sides. Framing the case is an ultra-resistant sapphire crystal 2 mm thick that shields the movement from everyday shocks and scratches. The crown at 3 o'clock lets you set the hours, minutes, and date with ease. Finally, the screw-down caseback offers a full view of the movement through its transparent window and ensures water resistance up to 5 ATM.

The Dial

This round dial reveals a blue surface accented by a square pattern. Its sunray finish adds a brilliant shimmer that catches the eye at the wrist. At the center, two baton and skeleton hands in gray indicate the hours and minutes - short for hours, long for minutes. They are treated with Superluminova C1 for strong legibility in low-light environments. Completing the display is a slim white seconds hand and a date window at 6 o'clock. Around the dial, baton indices and recessed white Arabic numerals make time-reading a breeze. Finally, a minute track runs along the bezel, the brand name sits at 12 o'clock, and the collection name along with the movement type appear at 6 o'clock.

The Movement

This timepiece is powered by a Japanese automatic movement - specifically the Seiko NH35A caliber, which reliably drives the hands and date window. It features 24 jewels to minimize friction, beats at 21,600 vph, and delivers a power reserve of up to 41 hours.

The Strap

This model comes with two interchangeable straps so you can dial in the look that suits you best. Both measure 20 mm at the lug width, keeping you looking sharp all day long.

The first is a strap made from blue vulcanized rubber. Flexible and pliable, it delivers all-day comfort without compromise. It fastens with a silver pin buckle and measures 75 mm for the short end and 115 mm for the long end.

The second strap is crafted from gray stainless steel. Its links feature a brushed finish that ensures long-term durability and adds the perfect elegant touch to this model. Its deployment clasp keeps it securely on your wrist. It measures 156 mm in length.

Water Resistance

With water resistance of 50 meters - or 5 ATM in watchmaking terms - this is a timepiece that handles water just fine, but isn't built for prolonged exposure. You can wear it in the shower occasionally, but to keep the movement running accurately and reliably, watch specialists strongly advise keeping it away from baths, pools, and the sea. In short: no swimming, no diving, and no extended contact with water.
