Tips & Answers for the Maintenance, Safety, and Reassembly of your Automatic Watches
This FAQ compiles answers to the most common questions regarding delivery, warranty, maintenance, compatibility, payment, and customization of our watch winders and safes. Our team is available Monday to Friday, from 9 AM to 5 PM, for any specific questions about your collection or installation.
1. Shipping & Returns
Mercier & Fils watch winders are shipped with free delivery. Exact delivery times are indicated during the order process and may vary depending on the finish selected and the destination country.
You will receive a shipping confirmation with a tracking number as soon as your order is dispatched.
Safe delivery is carried out by our logistics team. It includes curbside drop-off.
Installation is possible with every safe. Three elements must be checked before delivery:
- A floor capable of supporting the safe's weight (from 235 kg to 800 kg depending on the model).
- A nearby electrical outlet to power the winding modules.
- Sufficient clearance for door opening.
Yes, we deliver to mainland France, several European countries, and other international destinations. For any inquiries, please contact our team, who will discuss suitable delivery options.
Non-customized watch winders can be returned within thirty (30) days of receipt. The product must be returned in its original condition, with its packaging and accessories.
Given their weight, dimensions, and custom finishes, safes are subject to specific terms. We invite you to validate your project with our team before ordering so that every parameter (model, finish, access, anchoring) is confirmed. Safes are not eligible for return.
Each product is inspected before shipping. If you notice any anomaly upon receipt, report it immediately to our team. We will promptly arrange for replacement or repair as appropriate.
2. Warranty
Each Mercier & Fils safe is covered by a 5-year warranty covering:
- The safe's structure.
- The opening systems (BioLock®, code, emergency key).
- The integrated watch winder modules.
Watch winders come with a warranty against manufacturing defects. The exact terms will be specified at the time of order. Our team remains available after delivery for any adjustments or assistance.
Our team remains at your disposal after delivery for:
- TPD adjustments for new watches.
- Technical assistance.
- Configuration adjustments.
The warranty covers manufacturing and material defects affecting the structure, opening systems, and winding modules. It applies under normal and compliant use of the product. The warranty cannot be applied in the event of accidental damage.
The warranty is attached to the product and the original customer. For any transfer or resale, please contact our team to check the applicable conditions.
Contact our team (Monday to Friday, 9 am–5 pm) describing the problem. We will arrange the diagnosis, then the repair or replacement of the affected parts according to the terms of the warranty.
3. Maintenance & Care
Use a dry or slightly damp microfiber cloth to dust surfaces. Avoid solvents, abrasive products, and alcohol-based cleaners, which can damage finishes (ebony, full-grain leather, Alcantara, carbon fiber).
Gently wipe the reader with a dry microfiber cloth. Do not use any liquid or chemical products. The reader recognizes your fingerprint in less than 1.5 seconds; regular cleaning maintains this optimal performance.
Coil Winding® modules are designed for quiet and long-lasting operation (10 - 15 dB). No mechanical maintenance is required under normal use. If you notice abnormal noise or irregular rotation, please contact our team.
Ensure a stable temperature, away from direct heat sources, excessive humidity, magnetic fields, and prolonged light. Safes provide physical protection against shocks and theft; a stable environment also preserves movements.
Yes, that is precisely the intended use. The rotation cycles include rest phases that reproduce the natural rhythm of the wrist, without excessively straining the movement. The watch remains wound and ready to be worn.
Avoid prolonged exposure to sunlight and abrupt changes in humidity. For full-grain leather, a soft cloth is sufficient. For wood finishes (ebony, macassar), regular dusting with a microfiber cloth will preserve the luster of the surface.
4. Product Compatibility
Our watch winders are designed for automatic watches. The vast majority of movements operate optimally between 650 and 1,000 TPD in bi-directional rotation. Our database covers over 5,800 movements and 86 brands, allowing us to provide you with recommended settings for your watch(es). Mercier & Fils watch winders operate with a precise setting of 650 to 2200 turns per day (TPD).
Each position is individually programmable in TPD and direction of rotation (clockwise, counter-clockwise, bi-directional). Consult our database of 5,800 calibers, or contact our team for a custom setting. As a guide, a bi-directional setting at 800 TPD suits the vast majority of modern calibers.
Flex Mount® cushions fit all wrist sizes, thanks to their telescopic cushion allowing for an adjustment of 4 to 6 cm in diameter, and accommodate cases up to 55 mm. Your watches are held firmly, without vibration or wave transfer to the movement.
Yes. Each slot is independent: you can configure a different TPD and direction of rotation for each watch. A Rolex Submariner (650 TPD, bidirectional) and an Audemars Piguet chronograph (clockwise rotation) can coexist in the same device with their respective settings.
This is a real risk with entry-level winders. All our motors incorporate anti-magnetic technology and are designed to preserve the integrity of the hairspring, even on calibres most sensitive to magnetic fields.
No. Quartz watches do not need winding. However, our safes offer dedicated storage for quartz watches, cases, and documents, in addition to the winder slots.
No. Modern automatic watches incorporate a safety device (clutch) that engages as soon as the mainspring is fully wound. The winder continues to turn without transmitting additional energy: over-winding is mechanically impossible.
Yes. Our watch winders are particularly recommended for complicated watches (perpetual calendar, moon phases, tourbillon, minute repeater), as they require continuous winding to avoid losing their settings. Our team provides free adjustment advice for specific calibers and grand complications.
5. Secure Payment
Payment is made with Shopify Payments® and Stripe®, secure and encrypted payment platforms. Your bank details are never stored on our servers. Accepted payment methods are displayed at checkout and may vary depending on your country. We accept most credit card payment methods such as American Express, Visa, Mastercard, as well as other popular methods like Apple Pay, and PayPal.

Yes, with Klarna and PayPal, subject to approval.
Yes, an invoice is issued for each order. It is available in your customer area after your purchase has been validated.
All transactions are encrypted and processed by certified payment providers. We comply with current security standards (PCI-DSS) to guarantee the protection of your data at every step of the process.
6. Customization
Yes. Each product is offered in a consistent and limited range of finishes:
- Watch Winders: carbon fiber, ebony, glossy ebony, macassar, full-grain leather, alcantara, Tiphaine finish.
- Safes: Daytona (carbon), Tiphaine (blue leather, limited edition), Soleil Blanc, Nocturne (blue), Cocoa (brown leather).
We do not offer an open configurator: each finish is selected and validated to preserve the aesthetic coherence and quality of the product.
Yes, it is entirely possible to modify the number of existing winders to create the configuration that suits your needs.
We recommend adding 50% to 100% to your current number of watches:
- For 6 watches, choose a box with at least 12 slots.
- For 10 watches, aim for 16 to 20 slots.
Unoccupied slots cost nothing and are ready for your future acquisitions. Each slot is independent and requires no additional setup.
Yes. Several watch winders can be combined to create a coherent and scalable set. The range extends from the Mazarin II (2 watches) to the Rivoli XXIV (24 watches), allowing it to accompany the growth of your collection.
Yes. Each slot is independently programmable in TPD (from 650 to 2,200 rotations per day) and rotation direction (clockwise, counter-clockwise, bi-directional).
This customization allows each slot to be adapted to the exact caliber of the watch it holds.
Yes, for specific safe projects (non-standard dimensions, finishes, capacities), please contact our team.
We study each request on a case-by-case basis to assess the feasibility of implementation.
