The details behind the choice

Swiss precision or German manufacture

The NauticMaster brings together two movement concepts: Swiss Sellita calibres in the Swiss Edition and the German Damasko A26.2 Top in the Manufacture Edition.

New to the Swiss Edition: the NauticMaster Viator GMT, powered by the Sellita SW330-2 Elaboré and featuring a unidirectional 24-hour bezel with 96 click positions. The combination of the GMT function and the bezel allows three time zones to be displayed simultaneously, as well as the tracking of all 38 global time zones.

The Damasko A26.2 Top remains the technical heart of the Manufacture Edition. With around 90% of its manufacturing carried out in Germany, exclusive design details and an optional three-piece soft-iron cage with a steel caseback, it stands for a distinctive technical approach.

The classic Diver and Field Diver models in the Swiss Edition are powered by the proven Sellita SW200-1 Elaboré.

Swiss Made

SW200-1 – Proven Swiss precision

The Sellita SW200-1 is a classic, reliable automatic movement made in Switzerland. It displays hours, minutes and seconds and features a date function. In the NauticMaster, the crown offers four positions:

Screwed-down crown position
Manual winding
Quick date correction
Time setting

The stop-seconds function allows precise time setting. Like the A26, the SW200-1 features a ball-bearing mounted rotor for efficient winding with every movement.

Damasko A26.2 Top movement for Findeisen

Made in Germany

A26 – Innovation in perfection

At the heart of this masterpiece lies a completely redesigned automatic unit. Equipped with a click winding system, it efficiently converts even the smallest rotor movements into energy for the mainspring.

The innovative click winding mechanism works on a bearing-within-bearing principle: it runs on a ceramic ball bearing along a circular path and is itself supported in a full-ceramic ball bearing. Even the manual winding via the crown rests on hardened steel discs.

All components of the A26 are hardened, virtually wear-free and low-maintenance. The tungsten rotor is additionally fitted with a ceramic ball bearing to further minimise wear.

Optionally, the NauticMaster case can be fitted with a three-piece soft-iron cage that provides additional magnetic shielding for the calibre. The A26 calibre is mounted in a special EPDM rubber suspension, significantly exceeding the DIN 8308 shock-resistance standard.

Configuration

Your preferences. Our options.

Alongside your choice of movement, you can tailor your NauticMaster in several key areas to suit your personal preferences. We deliberately offer options only where they make a genuine difference to comfort, functionality or the character of your watch.

Straps & clasps

Whether you prefer a classic stainless steel bracelet, a sporty rubber strap or a versatile hybrid strap, each option gives your NauticMaster a distinct appearance. That's why every version has been purpose-built for its intended use. Naturally, all straps feature a tool-free quick-release system.

Stainless steel Block Bracelet

For those who appreciate the timeless feel of a solid stainless steel bracelet.

Our newly developed Block Bracelet in bead-blasted stainless steel combines timeless design with thoughtful modern details. Female end links provide a more natural fit on the wrist, while the newly designed compact IronLock clasp features an integrated micro-adjustment of up to eight millimetres – discreetly concealed and completely tool-free.

Rubber strap

For those who expect maximum performance – on land and underwater.

The durable FKM rubber strap features a bead-blasted clasp with integrated micro-adjustment for everyday wear, as well as a built-in diver's extension with additional fine adjustment. This allows the strap length to be adapted quickly to changing conditions – without compromising stability or wearing comfort.

Hybrid strap

For those who value versatility and everyday comfort.

Combining sailcloth on the outside with FKM rubber on the inside, the hybrid strap blends the classic look of a textile strap with the durability and water resistance of modern rubber. A brushed pin buckle completes its authentic look.

The bezel. The character.

Few components define the character of a wristwatch as much as its bezel. That's why the NauticMaster is available with either a bead-blasted stainless steel bezel or a black DLC insert. The shape remains the same – the character changes.

Bead-blasted stainless steel

Classic. Timeless. Authentic.

The one-piece bead-blasted stainless steel bezel gives the NauticMaster a timeless and authentic appearance. Its matte finish blends seamlessly with the case and emphasises the watch's clean design.

Black DLC insert

Technical. Bold. High-contrast.

The bezel with its black DLC insert creates a deliberately sportier look. The extra-hard DLC coating provides outstanding durability and emphasises the NauticMaster's distinctive technical character.

The crown. Your choice.

The position of the crown influences not only how a wristwatch is operated but also how comfortably it is worn. That's why every NauticMaster model with the date at 6 o'clock is available with either the classic right-hand crown or, optionally, a left-hand crown. The choice is yours.

Optional left-hand crown

Left-handed wearers in particular, as well as many pilots and divers, prefer a left-hand crown. It prevents direct contact with the back of the hand and provides additional comfort during certain movements. That's why it is available at no extra cost on all NauticMaster models with the date at 6 o'clock. Simply add your preference in the comments field on the product page.

NauticMaster White with DLC bezel and red rubber strap on the wrist

Classic crown position

The right-hand crown has been the traditional position in watchmaking for decades. It offers familiar operation and remains the preferred choice for most watch wearers.

Designed with purpose.

Inspired by the shape of a ship's propeller, the distinctive turbine bezel combines function with a unique design.

Turbine bezel

Secure grip. Distinctive design.

Its striking geometry ensures a secure grip – even with wet hands or gloves. Its shape was never accidental but evolved from the idea of combining function and design.

NauticMaster Khaki with DLC bezel and clear sapphire crystal

Anti-reflective crystal

Clear vision. At all times.

A watch should display the time – not reflect its surroundings. That's why we use sapphire crystal with anti-reflective coating on both sides for consistently clear legibility.

Legibility

Even in the dark.

Generously applied high-grade Super-LumiNova® on the hands and indices ensures quick orientation, even in low-light conditions.

Proportions

Robust without feeling bulky.

The NauticMaster's proportions have been balanced to give it presence without appearing unnecessarily massive – on the wrist and in everyday life.
