Description
A beautiful FORMEX Reef 39.5mm "Baby Reef" with a stunning blue dial.
Purchased directly from the official FORMEX website in January 2025, this watch has been lightly used and remains in excellent overall condition.
The Reef combines the functionality of a professional dive watch with the refined appearance of a luxury sports watch. Its relatively slim 11mm case, alternating brushed and polished finishing, and compact 39.5mm diameter give it a sophisticated presence on the wrist while retaining genuine dive-watch capability.
The blue dial features a beautiful gradient and changes character depending on the lighting and viewing angle, creating an especially attractive visual effect.
The watch is powered by the Swiss Made Sellita SW300-1 automatic movement in Chronometer grade, officially certified by COSC, with approximately 56 hours of power reserve.
One of the standout features of the Reef is its tool-free interchangeable bezel system. This particular set includes both the original blue ceramic bezel and stainless-steel bezel, allowing the appearance of the watch to be changed easily. FORMEX specifically highlights the tool-free bezel exchange system as one of the defining features of the Reef.
The watch also offers 300m / 1000ft water resistance, sapphire crystal, and a 45.5mm lug-to-lug dimension, making the 39.5mm case highly wearable despite its substantial dive-watch specifications.
The original 3-year FORMEX manufacturer warranty remains valid, as the watch was purchased in January 2025.
