AI-assisted summary
Description from the seller
Arcaido: time carved in bronze. The Italian experience, since 1993, meets Swiss Made craftsmanship and a living material that develops a unique, unrepeatable patina for whoever wears it.
In this auction we offer: Arcaido - Primo GMT Bronze - Swiss Made - Sellita SW330 Special Élaboré - Diver 300M - 42.5 mm - Bronze Marine Massello CuSn6 - Sapphire & Ceramic Bezel
42.5 mm Swiss Made GMT diving watch in solid marine bronze CuSn6, unidirectional 120-click bezel with a matte black ceramic insert, anti-reflective sapphire crystal, exhibition case back, decorated Swiss automatic movement with second time zone, 30 ATM/300 m water resistance, Made in Italy leather strap. Luxury box with a second NBR rubber strap and a toolkit for interchangeability. New with documents and official 2-year warranty.
Primo GMT Bronze is a diver built with a material that almost no one truly uses: solid marine bronze CuSn6, the alloy used in naval environments to resist seawater. Not a coating, not a surface treatment applied to steel: case, bezel and crown are bronze through and through, from the outside to the core.
This is what makes each specimen different from all the others. Bronze reacts to air, to skin, to seawater, and over time develops a patina that no other watch will have: it darkens in the engravings, it lightens where the sleeve rubs it to polish it. Whoever buys an Arcaido is not buying a finished object, but an object that continues to work.
The GMT function allows reading a second time zone thanks to a fourth central hand, paired with the 24-hour scale printed on the dial: home time remains on the main hands, the second time zone is read on the 24-hour scale, with quick time-zone and date adjustment. A tool designed for travelers who want to keep two times under their eyes.
The construction is that of a true instrument. Three hundred meters of water resistance, unidirectional 120-click bezel with matte black ceramic insert — raised numbers and scale, a material that does not scratch or stain — anti-reflective sapphire glass, black dial with applied indices and Swiss Super-LumiNova BWG9, white in daylight and blue in the dark.
The exhibition case back in 316L steel with sapphire allows you to observe the Swiss automatic movement at work: circular grain decorations, blued screws and a customized IP black rotor that spins with every wrist movement. It is a finish that is usually not found in this price range, and here it is not hidden under a closed case back.
The strap is Made in Italy leather, hand-stitched and interchangeable thanks to two removable end-links. In the luxury box you’ll find the second strap in NBR rubber and the complete toolkit: the bronze buckle is a single piece and shifts from one strap to the other with the included kit. The case and the buckle are in the same bronze and develop the same patina together. Leather for everyday wear, rubber for 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.
