SELLITA SW200-1 — 26-JEWEL SWISS AUTOMATIC MOVEMENT

At the heart of this professional Squale diver is the proven Sellita SW200-1 Swiss automatic mechanical movement.

VERY IMPORTANT — THIS WATCH HAS NEVER BEEN OPENED

MOVEMENT PHOTOGRAPHS ARE STOCK / REFERENCE PHOTOS ONLY

This particular watch has never been opened since it left the manufacturer in Switzerland.

The caseback has not been removed by me, and I have intentionally kept the watch closed rather than opening it simply to photograph the movement.

Any photographs in this listing showing an exposed Sellita SW200-1 26-jewel automatic movement are STOCK / REFERENCE PHOTOGRAPHS ONLY.

They are included solely to illustrate the type and design of the movement specified for this watch model.

PLEASE NOTE:

  • The movement photographs are NOT photographs of the actual movement inside this individual watch.
  • This individual watch remains unopened.
  • The movement has not been removed from this watch for photography.
  • Rotor engraving, decoration, finishing and minor cosmetic details may differ from the reference movement photographs.
  • Actual exterior watch photographs show the watch being offered unless specifically identified as a stock/reference image.

This disclosure is included to avoid any misunderstanding and to preserve the originality of the watch.

 

PROFESSIONAL 50 ATM / 500-METER DIVE CASE

The Squale 50 Atmos platform was developed as a serious professional diving watch rather than simply a fashion-oriented sports watch.

Case Material: Stainless Steel
Case Diameter: Approximately 42 mm
Case Thickness: Approximately 16 mm
Lug-to-Lug: Approximately 49 mm
Lug Width: Approximately 20 mm
Caseback: Solid screw-down stainless-steel caseback
Water Resistance: 500 meters / 50 ATM

The substantial case construction gives the watch the unmistakable presence of a classic professional diving instrument.

 

DISTINCTIVE SINGLE CROWN AT APPROXIMATELY 4 O’CLOCK

An important feature of this model is its unusual protected crown position.

The watch has one main screw-down winding crown positioned at approximately the 4 o’clock location.

This crown position is part of the characteristic case design and helps protect the crown while also improving wrist comfort.

Please refer to the actual close-up photographs of this watch for the exact case and crown configuration.

 

SAPPHIRE CRYSTAL

Crystal Material: Sapphire
Anti-Reflective Treatment: Yes
Design: Heavy-duty professional diving construction

Sapphire crystal offers excellent scratch resistance and long-term optical clarity.

 

SAPPHIRE PROFESSIONAL DIVE BEZEL

The watch features a substantial rotating diving bezel designed for elapsed-time measurement.

Bezel Type: Unidirectional rotating dive bezel
Insert: Sapphire
Scale: 60-minute diving scale
High-Visibility Markings: Yes

The sapphire bezel insert gives the watch a more substantial and luxurious appearance while also offering excellent durability.

 

PROFESSIONAL DIVE DIAL

The striking dial provides excellent contrast and underwater-style visibility.

Features include:

  • Large luminous hour markers
  • Highly visible hour and minute hands
  • Distinctive orange accent hand
  • Central seconds
  • Date window
  • Squale branding
  • DRASS / Galeazzi designation
  • Swiss Made marking
  • High-visibility luminous treatment

The design reflects the primary requirement of any true dive watch: fast and easy readability.

 

500 METERS / 50 ATM WATER-RESISTANCE RATING

The 50 Atmos designation corresponds to a factory-rated water resistance of approximately:

500 meters
1,640 feet
50 ATM

This places the model firmly within the serious professional-diving category.

IMPORTANT WATER-RESISTANCE NOTICE

Because this is a pre-owned mechanical watch, I recommend having the watch professionally pressure-tested before intentional swimming or diving if the buyer intends to use it underwater.

No guarantee of current water resistance is made unless a current pressure test is specifically documented.

 

SQUALE DIVING HERITAGE

Squale has a long history closely connected with professional diving watches and specialized diving-watch cases.

The company became particularly well known for producing robust cases and purpose-built watches intended for demanding underwater environments.

Collectors often recognize Squale for its distinctive case designs, highly legible dials and professional diving heritage.

The DRASS Galeazzi collaboration takes that history a step further by connecting Squale with another historic name associated with professional subsea engineering.

 

ABOUT DRASS GALEAZZI

DRASS and Galeazzi have historic associations with professional underwater and subsea technology.

That makes this collaboration particularly appropriate.

Rather than being merely a cosmetic limited edition, the watch links two names with genuine connections to the underwater world:

SQUALE — Swiss professional diving watches

DRASS GALEAZZI — professional subsea and diving technology

This background gives the watch additional appeal for collectors interested in professional diving history, mechanical watches and unusual limited-edition collaborations.

 

LIMITED TO ONLY 500 PIECES WORLDWIDE

Only 500 examples of this special edition were produced.

Limited production is one of the strongest collector attractions of this model.

Unlike standard-production watches that may remain available for many years, a 500-piece worldwide run means relatively few examples can appear on the secondary market at any one time.

This offering includes the watch and the accessories shown in the actual photographs.

INCLUDED WITH THE SALE:

  • Squale × DRASS Galeazzi 50 Atmos automatic watch
  • Stainless-steel mesh / Milanese-style bracelet
  • Additional blue strap

  • Limited-edition engraved caseback
