Briston crafts authentic, refined watches that bring the perfect finishing touch - whether your style is sharp or laid-back. Its pieces are built from premium materials for results that are as beautiful as they are built to last. From its Streamliner Urban Auto collection comes this stunning men's watch in silver, designed to exceed your expectations on every level. The barrel-shaped case is made from stainless steel and cellulose acetate for lasting durability and all-day comfort. For added elegance, it features a bezel secured by four screws, with a mirror-polished edge and a brushed surface. At 40 mm in diameter and 12.80 mm thick, the case offers a dial opening of 31.50 mm, protected by an ultra-resistant 2 mm sapphire crystal that shields the dial from scratches and impacts. You can easily set the hours, minutes, and date using the crown at 3 o'clock. The movement is protected by a screw-down caseback with a transparent window revealing the rotor. Water resistance reaches 5 ATM.
Round in shape, this dial features a blue background with a square pattern and a sunray finish that enhances time readability. The bezel reveals a minute track, while the center houses two hands indicating hours and minutes - short and long respectively. Both are coated with SuperLuminova C1 for excellent legibility even in low-light conditions. They sweep over white Arabic numerals and indices in relief along the dial's perimeter, making time reading effortless. The seconds are displayed by a white seconds hand, and the date appears in a window at 6 o'clock. Finally, the brand signs the model at 12 o'clock and the collection name is noted at 6 o'clock.
Powering this timepiece is a Japanese automatic movement. The Seiko NH35A caliber features 24 jewels and beats at a frequency of 21,600 vibrations per hour. Highly reliable, it delivers a power reserve of 41 hours and drives the central components with precision and energy.
This watch comes with two interchangeable straps, each giving the watch an entirely different look. Both offer excellent comfort and measure 20 mm in width at the lug.
The first is a blue vulcanized rubber strap. Highly flexible, it delivers optimal comfort on the wrist and pairs effortlessly with any style. It fastens with a gray pin buckle and measures 75 mm for the short end and 115 mm for the long end.
The second strap option is crafted in brushed stainless steel. Its silver tone makes it easy to pair with a wide range of outfits, adding an elegant finishing touch to this timepiece. It fastens with a deployant clasp and measures 156 mm in length.
With a water resistance of 5 atmospheres - equivalent to 50 meters - this watch is a solid entry into the world of water-resistant timepieces. While it's not designed for bathing, competitive swimming, or scuba diving, you can safely forget to take it off in the shower. That said, our experts recommend keeping this timepiece dry to preserve its movement for years to come.
