AI-assisted summary
Description from the seller
Arcaido: time sculpted in bronze. Italian experience since 1993 meets Swiss Made craftsmanship and a living material that develops a unique patina, as one of a kind as the person wearing it.
For 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
42.5 mm Swiss Made GMT dive watch in solid CuSn6 marine bronze, 120-click unidirectional bezel with matte black ceramic insert, anti-reflective sapphire crystal, exhibition case back, decorated Swiss automatic movement with second time zone, water resistance to 30 ATM/300 m, Made in Italy leather strap. Luxury presentation box with a second NBR rubber strap and tool kit for changing straps. New, with papers and official 2-year warranty.
Primo GMT Bronze is a dive watch made from a material almost nobody really uses: solid CuSn6 marine bronze, the 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 made entirely of bronze, from the outer layer to the core.
That is what makes every example different from all the others. Bronze reacts to the air, the skin, and salt water, and over time develops a patina unlike that of any other watch: it darkens in the engravings and lightens where friction from a sleeve polishes it. Buying an Arcaido means buying not 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 travelers who want to keep track of two times at a glance.
This is the construction of a true instrument. Water resistance to 300 meters, a 120-click unidirectional bezel with a 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 markers and Swiss Super-LumiNova BWG9, white in daylight and blue in the dark.
The exhibition case back 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 in this price range, and here it is not hidden beneath a closed case back.
The strap is Made in Italy leather, hand-stitched and interchangeable thanks to the two removable end links. The luxury presentation box includes a second 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 supplied kit. The case and buckle are made of the same bronze and develop the same patina together. Leather for everyday wear, rubber for the water.

Seller's Story
Arcaido is our challenge: With 30 years of watchmaking expertise, we create high-quality, affordable products.
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. As the new millennium approached, our business offering expanded to incorporate design. We successfully started designing and manufacturing watches for clients worldwide. 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.
