AI-assisted summary
Description from the seller
Arcaido: time sculpted in bronze. Italian heritage, since 1993, meets Swiss Made craftsmanship and a living material that develops a unique patina, as individual as the person wearing it.
In this auction, we are offering: Arcaido - Primo GMT Bronze - Swiss Made - Sellita SW330 Special Élaboré - Diver 300M - 42.5 mm - Solid CuSn6 Marine Bronze - Sapphire & Ceramic Bezel
Swiss Made 42.5 mm GMT dive watch in solid CuSn6 marine bronze, 120-click unidirectional bezel with matte black ceramic insert, anti-reflective sapphire crystal, exhibition caseback, decorated Swiss automatic movement with second time zone, water resistance to 30 ATM/300 m, Made in Italy leather strap. Luxury presentation box with an additional NBR rubber strap and tool kit for changing straps. New, with papers and a 2-year official warranty.
Primo GMT Bronze is a dive watch made from a material that almost nobody actually uses: solid CuSn6 marine bronze, an alloy used in marine environments to withstand salt water. Not a coating, not a surface treatment applied to steel: the case, bezel and crown are bronze all the way through, from the outer layer to the core.
This is what makes every piece different from all the others. Bronze reacts to the air, the skin and salt spray, and over time develops a patina unlike that of any other watch: it darkens in the engravings and lightens where the rubbing of a sleeve polishes it. When you buy an Arcaido, you are not buying a finished object, but one that continues to evolve.
The GMT function lets you read a second time zone using a fourth central hand paired with the 24-hour scale printed on the dial: your home time remains on the main hands, while the second time zone is read on the 24-hour scale, with quick adjustment of the time zone and date. A tool designed for people who travel and want to keep track of two time zones at a glance.
This is the construction of a true instrument. Water resistance to 300 metres, a 120-click unidirectional bezel with matte black ceramic insert — raised numerals and scale, in a material that does not scratch or fade — sapphire crystal with anti-reflective treatment, black dial with applied indices and Swiss Super-LumiNova BWG9, white in daylight and blue in the dark.
The exhibition caseback in 316L steel with sapphire crystal lets you watch the Swiss automatic movement at work: circular-grain decoration, blued screws and a custom IP black rotor that turns with every movement of the wrist. This is a finish rarely found at this price point, and here it is not hidden behind a solid caseback.
The strap is handmade in Italy from leather and can be changed thanks to its two removable end links. The luxury presentation box includes an additional NBR rubber strap and a complete tool kit: there is just one bronze buckle, which can be moved from one strap to the other using the included kit. The case and buckle are made from the same bronze and develop the same patina together. Leather for everyday wear, rubber for the water.

Arcaido became a reality in Balestra Studios, home to our family goldsmiths since 1993. Business-to-business watchmaking has been an integral part of our operations for decades. We have devoted thirty years to researching and driving the latest fashion trends, perfecting movements with the quality components – and sourcing the most finest materials.

Hard work, innovation and passion for new ideas, thanks in part to the dedication our founder’s son, we continue to push the possibilities for our company.
From the Italian word “arca”, which means “ark”, as a metaphor of a vessel of past knowledge and new ideas.
