Special forces watch Serica 5303 PLD

Starting from 1.690 €

The Serica 5303 PLD Amagnetic Diving Chronometer is a professional diving watch developed with the Amicale des Plongeurs Démineurs to meet the specific needs of underwater intervention specialists. Adapted from the 5303 Diving Chronometer, this PLD version stands out with its black enamel dial, abyss blue ceramic bezel with “DT MAX” scale, and strong 50,000 A/m anti-magnetic resistance. Its 39 mm 316L steel case remains compact while offering 300 metres of water resistance. Powered by the M100 COSC caliber, it combines chronometer-certified precision, enhanced legibility and genuine rarity, as this limited-series model is now difficult to obtain.

Serica 5303 PLD Amagnetic Diving Chronometer diving watch

Serica builds its watches around a clear idea: creating reliable, legible and elegant mechanical instruments without sacrificing a distinctive watchmaking personality. The 5303 PLD Amagnetic Diving Chronometer follows this approach, but with a far more specialised dimension than the standard 5303. Developed in collaboration with the Amicale des Plongeurs Démineurs, it adapts Serica’s emblematic diving watch to the needs of underwater intervention professionals, especially in contexts where legibility, precision and resistance to magnetic fields become essential.

Unlike a simple edition inspired by the military world, the 5303 PLD is directly connected to the universe of French mine clearance divers. These specialists operate in particularly demanding environments during sensitive underwater missions. This operational vocation explains the choice of an anti-magnetic, robust and highly legible watch, designed as a true mission instrument rather than a purely aesthetic tribute.

This PLD version retains the compact format that makes the 5303 collection so appealing: a 39 mm steel case, 12.20 mm thickness, 300 metres of water resistance and a double-domed sapphire crystal. But it also introduces elements specific to its intended use: an abyss blue ceramic bezel with “DT MAX” scale, a black enamel dial marked “Amagnetic Chronometer” and a large “Fat Lollipop” seconds hand designed as a more visible running indicator. The watch is also offered with a crown at 3 o’clock or 9 o’clock, a woven steel bracelet in Small or Standard size, and a green or blue SERICA PLD strap depending on configuration. Produced as a limited series, it ranks among the rarest and most specialised versions of the Serica 5303.

The Serica 5303 PLD Amagnetic Diving Chronometer diving watch

The Serica 5303 PLD Amagnetic Diving Chronometer takes the architecture of the 5303 and gives it a more professional, more military-oriented identity. Its 316L steel case measures 39 mm in diameter, 12.20 mm thick and 46.50 mm lug-to-lug. These dimensions remain very restrained for a diving watch water-resistant to 300 metres, allowing it to retain real versatility on the wrist. The case alternates polished and satin-brushed surfaces, in the Serica spirit: technical enough to evoke a proper instrument, yet refined enough to avoid a purely austere tool-watch look.

This PLD version stands out above all through its visual and functional identity. The black enamel dial features domed indexes filled with Super-LumiNova C3, paired with white lacquered hands. The large Fat Lollipop seconds hand improves the visibility of the running indicator, an important detail on a watch designed for underwater use. The abyss blue ceramic bezel introduces a “DT MAX” scale, designed to provide direct reading of maximum working time according to depth. The watch can be configured with a crown at 3 o’clock or 9 o’clock, allowing the wearer to choose between a classic layout or a more comfortable solution depending on wrist and use.

An amagnetic diver designed for mine clearance divers

The Serica 5303 PLD stands out through its technical coherence. It is powered by the M100 COSC caliber, a Swiss mechanical self-winding movement with 25 jewels, regulated according to chronometer certification standards. Its frequency of 28,800 vibrations per hour ensures smooth running, while its 42-hour power reserve remains suitable for daily use. The Côtes de Genève finishing adds a more refined watchmaking touch, even if the main interest of this model lies in its instrument-focused vocation.

The 50,000 A/m anti-magnetic resistance is central to this PLD version. In the world of mine clearance divers, an amagnetic mechanical watch is not merely an aesthetic or traditional choice: it responds to a safety logic linked to environments sensitive to magnetic signatures. The “Amagnetic Chronometer” marking on the dial underlines this orientation. The woven steel bracelet with integrated end pieces gives the watch a strong Serica presence, while the green or blue SERICA PLD Strap extends the inspiration of historic straps used by French divers. The result is a highly specialised, rare and strongly identifiable diving watch combining precision, legibility, professional water resistance and a clear military identity.

Serica 5303 PLD Amagnetic Diving Chronometer diving watch: mission instrument

The Serica 5303 PLD Amagnetic Diving Chronometer is a 39 mm automatic diving watch developed with the Amicale des Plongeurs Démineurs. Water-resistant to 300 metres, it features a 316L steel case, an abyss blue ceramic bezel with “DT MAX” scale, a black enamel dial and a double-domed sapphire crystal. Its M100 COSC caliber delivers chronometer-certified precision, while its 50,000 A/m anti-magnetic resistance strengthens its technical relevance. Produced in limited quantities, this PLD version stands as one of the rarest and most distinctive expressions of the Serica 5303.

01

Movement

The Serica 5303 PLD is powered by the M100 COSC caliber, a Swiss automatic movement with 25 jewels, regulated according to official chronometer standards. It beats at 28,800 vibrations per hour, offers a 42-hour power reserve and features Côtes de Genève finishing. This mechanical base gives the watch genuine horological legitimacy, beyond its identity as a professional diver. The COSC certification is particularly consistent with the spirit of the model, built around precision, reliability and legibility in demanding conditions.

02

Diameter and materials

The Serica 5303 PLD case measures 39 mm in diameter, 12.20 mm thick and 46.50 mm lug-to-lug. These dimensions remain compact for a diving watch water-resistant to 300 metres, improving comfort both in daily wear and under a wetsuit. The 316L steel alternates polished and satin-brushed finishes, while the bezel receives an abyss blue ceramic insert. This mix of materials gives the model a more technical presence than the classic 5303, without sacrificing Serica’s characteristic elegance.

03

Water resistance

With its 300 metres / 30 ATM water resistance, the Serica 5303 PLD retains a true professional diving-watch vocation. Its ceramic bezel uses a dual “DT MAX” scale, designed to quickly read maximum working time according to depth. This approach sets it apart from a more traditional diving bezel limited to simple minute tracking. The watch therefore remains suitable for classic nautical use, while asserting a more specialised orientation linked to underwater intervention.

04

Accessories

The Serica 5303 PLD is offered with a woven steel bracelet featuring integrated end pieces and hinged links. It is available in Small size for wrists from 13.5 to 17.5 cm and in Standard size for wrists from 15.5 to 21.5 cm. The watch can also be configured with a green or blue SERICA PLD Strap, inspired by historic straps used by French divers. This second option reinforces the military and professional character of the model, while providing a softer and more distinctive alternative to steel.

05

Warranty

Serica covers the 5303 PLD with a 2-year international warranty from the date of receipt. This warranty applies under the brand’s stated conditions and supports the watch’s premium positioning. The official product information also mentions the possibility of return within 14 days after receipt. For a COSC-certified diver, water-resistant to 300 metres and equipped with 50,000 A/m anti-magnetic resistance, this warranty reinforces the coherence of a mechanical instrument built to last.
