Description
The Heritor Pytheas is a utilitarian dive watch that leans heavily into military and vintage design cues. The matte green dial paired with 'cathedral' hands—usually found on field watches—creates a unique hybrid look. It is designed for the enthusiast looking for a substantial mechanical watch with a distinct personality that differs from the standard Rolex Submariner clones.
Key Features
Oversized 'Shark Tooth' applied indices, Cathedral-style hour and minute hands, and the matte olive green colorway which is a popular trend in modern tool watches.
Dial Description
Matte olive green dial with applied luminous triangular "shark tooth" indices. It features cathedral-style hands, a white lollipop seconds hand, and a rectangular date window at 3 o'clock.
Case Material
316L Stainless Steel with a brushed satin finish on the lugs and sides to minimize glint and hide scratches.
Crystal Type
Flat Mineral Crystal with sapphire coating. While more scratch-resistant than standard glass, it lacks the full scratch immunity of pure sapphire.

Unidirectional rotating 120-click dive bezel. It features a black aluminum insert with a 60-minute scale and a luminous pip at the 12 o'clock triangle.
Crown & Pushers
Screw-down crown located at 3 o'clock. It is knurled for grip and features the Heritor brand logo on the flat end. No crown guards are present, giving it a vintage feel.

Rated at 200 Meters (20 ATM). This is suitable for recreational scuba diving, swimming, and snorkeling, provided the gaskets are maintained annually.

Care & Maintenance
Service every 5-7 years for the movement. Ensure the crown is fully screwed down before any water contact. Rinse with fresh water after exposure to salt for the bezel and bracelet.
