Como™ Single Watch Winder - Black
A compact winder for one automatic watch
The black Como winder accommodates one automatic watch in a case finished with vegan leather and velvet. Designed for an office, dresser, or shelf, it takes up minimal space while ensuring consistent TPD winding between wears.
5 TPD settings to suit every caliber
The Como winder offers five turns-per-day settings: 650, 750, 850, 1000, and 1950. Each automatic caliber has its recommended winding cadence, and this step-by-step adjustment allows you to configure the winder according to the watch manufacturer's specifications, without over-winding or under-winding.
Coil Winding® Motor and Flex Mount® cushion
The Coil Winding® Technology motor ensures ultra-silent winding, less than 15 decibels, with protection against magnetism. Two cushion sizes are included to fit all wrist sizes.
Vegan leather, black finish
The vegan leather and velvet covering of the black Como reflects a commitment to alternative materials without compromising on finish. A winder designed for a first collection piece or nomadic use.

Each collection is unique. We are available to help you choose your display case.
A question? We are here.
Each Mercier & Fils case is an important decision. We have gathered the answers to the most frequently asked questions here — but our advisors remain available if you wish to speak directly.
Yes, we deliver everywhere in France and worldwide. Delivery costs are calculated at checkout. Each order is packaged with the utmost care to ensure the integrity of your piece upon delivery.
A watch safe is much more than just a storage unit. It protects your collection against theft, impacts, and humidity, while keeping your automatic watches wound with integrated winding modules. Designed for collectors who refuse to choose between security and care for their mechanics.
A watch winder keeps your watches running — that's it. A Mercier & Fils watch safe does that, and also physically protects your collection: solid steel structure, secure lock, optional floor or wall anchoring. For a valuable collection, a watch winder alone is not enough.
Yes. Our winder modules are adjustable in terms of direction (clockwise, counter-clockwise, bidirectional) and turns per day, to adapt to the specifications of each manufacturer—Rolex, Patek Philippe, AP, and hundreds of others. Consult our TPD guide to find your watch's settings.
Capacity, security level, and finish are the three main criteria. Our French advisors are available Monday to Friday to assist you with this choice—each collection is unique, and so is each recommendation.
