Relaunched with modern technology, this model is one of the most proficient professional diving watches on the market, an exemplary timepiece that serves as the flagship model for Delma’s series of diving watches
Made in the center of the Swiss watchmaking region in Lengnau, the Delma Quattro watch is a professional diving watch that is water-resistant to 500 meters/ 1650 feet or 50 atmospheres.
Unidirectional stainless steel black DLC diver bezel. Black dial, applied indexes, and Arabic numerals with luminous markers. Orange minute and seconds hand, white hour hand with luminous markers. Water-resistant to 50 ATM / 500 m / 1650 ft. Limited edition to 999 pieces.

The Delma Quattro is beautifully designed with its iconic orange indexes. The dial is clean and extremely easy to read with highlighted luminescent hour markers and luminescent hour and minute hands and an orange seconds hand.
While the second hand can be heard in the silence of the night from its resting place on a nightstand, it’s not a disturbing tic, tic, tic sound. It’s a minor consideration but a pleasant realization nonetheless.
This diver’s watch exceeds the standard ISO 6425 for professional diving watches and is equipped with a screw-down crown that guarantees resistance to humidity and water over the long term. This watch is also protected from damage caused by expanding helium molecules that lead to internal overpressure. This is thanks to an integrated helium valve that allows these molecules to escape.
