Key Features

Night Vision Aesthetic: Features a matte black Hard-coated stainless steel case and a grey dial. It uses high-intensity "Green LumiBrite Pro" for superior visibility in the dark.

The Strap: Its lightweight 87g build is due to thge textile/polyester strap. This makes it much lihgter than the steel-bracelet Prospex models.

Tortoise vs. Turtle: While it shares the rounded case shape of the Turtle, the "Tortoise" is designed as a land-based adventure watch, featuring a compass bezel instead of a diving scale.

Water Resistance: Despite being a "Land" model, it still maintains a solid 200m water resistance with a screw-down crown.

This model is a great choice if you're looking for low-profile, stealthy tool watch that doesn't feel heavy on the wrist during a full shift.
