A new expression of the Water Champion
From the Delfin of 1961 to the Hydro-Sub and today’s CO-1 line, Edox has built its name on water‑ready watchmaking. The CO-1 Date Automatic Bezel Lock continues this legacy as a focused diver for situations where timing must be exact.
Created on a platform originally conceived in 2006 for offshore powerboat racing, the watch is designed to cope with impact, vibration and demanding conditions. The 42mm stainless-steel case, ceramic bezel insert and sapphire crystal are selected for durability rather than display, so the watch feels like a professional tool that can still move easily from dive boat to desk.
The bezel lock: security under pressure
The defining feature of the CO-1 Bezel Lock Automatic is its bezel lock system. On a serious diver, an accidental bezel move can compromise timing, so Edox integrates a mechanism that prevents unwanted rotation during a dive.
Working with the scratch‑resistant ceramic bezel, the lock offers the assurance divers expect when tracking elapsed time underwater. The sapphire crystal reinforces this robustness, resisting scratches and impacts that quickly age a conventional sports watch and underlining the watch’s tool‑driven purpose.
Mechanical focus and depth-ready engineering
Inside the case, Edox uses the Caliber 80 (SW 200), a Swiss automatic movement chosen for reliability. It powers central hours, minutes, seconds and a date display, matching the watch’s straightforward, instrument-like character.
The movement is sealed by a solid case-back, contributing to a 300m / 30 ATM water-resistance rating suitable for genuine diving. A screw-down crown secures the case against water ingress, while a helium valve supports the watch in decompression phases encountered in professional environments. Generous Super‑LumiNova on the hands and indices keeps the display legible when natural light disappears, so elapsed time remains clear even on deeper descents.
With a 14mm case height and a weight of 140g, the CO-1 Bezel Lock Automatic has a tangible but controlled presence on the wrist. It feels compact and purposeful, designed to withstand pressure while remaining comfortable during long days around the water.
Within the CO-1 collection and Edox heritage
Within the broader CO-1 family, which in some references reaches depths up to 1000m, this Bezel Lock Automatic is a balanced proposal: professional specifications in a format suited to daily wear. Its €1,750 recommended price will appeal to enthusiasts seeking serious dive credentials without conspicuous luxury styling.
For Edox, a family-owned manufacture since 1884, the model reinforces the “Water Champion” identity that has shaped the brand for decades. Emphasis on high water resistance, complex cases and traditional hand assembly runs from historic Delfin milestones to today’s production in Les Genevez.
Why it matters
The CO-1 Bezel Lock Automatic channels Edox’s underwater experience into a modern, technically focused diver with a clear purpose. For GCC collectors who look for authentic performance allied to low-key refinement, it offers a Swiss-made option built to deliver below the surface and stay versatile above it.
