The Delma Quattro offers plenty of features to keep even the most discerning dive watch fanatic happy.

The Quattro is unapologetically utilitarian: fat lume plots, a heavy bezel and a strap you can rinse under a tap after a salty day.

Not many dive watches let you watch the movement work, and this one still carries a 50 ATM rating engraved around the window.

This is where a mechanical dive watch earns its keep: nothing to charge, nothing to pair, and a bezel you can still turn with a thick glove on.

Legibility underwater has nothing to do with lume charts. You get one glance mid dive, and either the dial answers or it does not.

Wreck dives are where a bezel earns its money. Ambient light drops, colour drains away, and everything on the dial has to still work in blue.

Open blue with no reference point is the hardest legibility test a dive watch gets. Contrast, not branding, decides whether you can read it.

The Delma Quattro offers plenty of features to keep even the most discerning dive watch fanatic happy, including a hidden, screw-down crown and the Rapid Bracelet Exchange System (RBES), which allows the wearer to easily switch from the bracelet to another strap—without any tools.

The unique symmetrical stainless steel case elegantly integrates the helium escape valve while protecting the screw-down crown, and the bezel features six notches to make it easy to adjust. With so much going for it, it’s easy to see why the Delma Quattro remains a firm favorite in the luxury dive watch category.

Delma Quattro dive watch with a black dial and green luminous markers on a rubber strap
The Quattro is unapologetically utilitarian: fat lume plots, a heavy bezel and a strap you can rinse under a tap after a salty day.

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.


Do we recommend it?
