1504 - 2240V
Diver's watch water resistant to 300 meters. This model is inspired by a major lunar eclipse in 1504 linked to Christopher Columbus, which proved to be an opportunity that saved his and his crew's lives. This timepiece is in fact designed to withstand stress, making it particularly suitable for those who practice water sports and guide you on your adventures.

Each of our watches is the result of an Italian production characterized by precision, artisan care and careful selection of materials. Every detail of our watches is made with passion and attention to the highest quality standards.
Precision and reliability
At 40mm in diameter and 13.7mm thick, the 1504 is versatile and comfortable on any wrist.
316L steel differs from other stainless steel alloys due to its high percentage of molybdenum which guarantees superior resistance to corrosion and atmospheric agents.
The crown and case back are screw-locked with gaskets that guarantee water resistance up to 300 metres.
The Seiko NH35A is the world's most reliable entry-level self-winding mechanical caliber. In 2022, the GMT complication variant is introduced with the ability to adjust the time zone hand separately from the other hands.
In our laboratory we give an additional control of the time on the chronocomparator and we have the possibility to intervene, to guarantee a more efficient performance of the calibers.

The 120-click rotating bezel is a key feature of all dive watches and dive times.
The K1 sapphire insert in various colors is highly resistant to scratches and corrosion , protecting the aesthetics of the watch.
The 1504 Automatic insert features a coating on all details of BGW9 Superluminova and C3 Superluminova at the zero point for easier reading in low-light environments.
Swiss Super-LumiNova® pigments are the exclusive choice of the Swiss watchmaking industry when it comes to achieving the highest possible luminance on a watch. The simple shapes of the triangular indexes and the large hour and minute hands ensure easy and reliable reading.
The shape of the indexes and hands is inspired by a fundamental element of the compass, the rotating magnetic needle, which always points to the same point on the horizon as it gets closer to north.
The caseback evokes the exploratory and adventurous spirit of Christopher Columbus through the engraving of the fourth and final expedition during which the famous lunar eclipse of 1504 took place.
The solid 316L steel clasp and bracelet feature a screw-down safety system to secure the links.
The shape provides strength and reliability for movements subject to strong stresses.
The bracelet finishes feature a bold satin finish to give it a more sporty and wear-resistant character . They are also finished with a mirror polish on each profile of the link.
