OW M-110 M

SFr. 1,596.00

The OW M-110 M – a tactical tool watch that draws on over 60 years of military and dive expertise. Combining many design characteristics, and the impermeability of OW’s original dive watches, with a 360-degree compass bezel more conventionally found on field watches.

In the absence of a magnetic compass, the US Army Ranger Handbook provides infantrymen detailed instruction on how to use the ‘watch method’ to get a bearing. This is a simple technique that involves lining the hour hand up with the sun, and then bisecting the distance between the hour hand and 12 o!clock position, to discover south.

Another distinctive feature of the OW M-110 M, which military users will recognise, are the radio silence period markers on the dial. These are three-minute periods immediately after each quarter hour, reserved exclusively for making – and listening for – distress calls.

The OW M-110 M, is the first OW watch to carry the new Soprod Newton Precision movement.The result of a close collaboration between OW and Soprod, the new movement is a bespoke version of the Newton P092, modified to OW’s own specifications and adjusted in five positions. It has been finished in accordance with our rugged aesthetics, and ‘OW Zurich 1956’ is engraved into the nickel- plated base, on which sits a co-designed, custom rotor in the shape of the OW marque. The inimitable new movement will carry OW’s own ‘PRECISION’ rating, reserved for movements of only the highest quality.

The OW M-110 M also sees the return of the classic ‘skin diver’ case, first used on early OW models such as the 1964 Aquaguard and the 1965 Early Bird. The OW M-110 M features a heavy-gauge, stainless steel mesh bracelet with reinforced ends and hand-brushed finish. A great amount of care has gone into the development of this new bracelet, in line with OW’s historical approach. As well as being virtually indestructible and fit for professional use, we believe it is our most comfortable bracelet yet. The sturdy milled and engraved clasp is extendable up to 22 mm, and a double pusher-release system provides extra security against accidental opening.

Wherever you're headed, whatever journey you're on and whatever the objective, the OW M-110 M will help you navigate any challenge.

Please note the stainless steel mesh bracelet should always be adjusted by a competent watchmaker.
