A leather strap can last 5, 8, even 12 years of daily wear. But the difference between a strap that ages well and one that deteriorates in two months comes down to one thing: the cleaning routine. Nothing expensive is required, nothing complicated. What is needed is five minutes a week and a few gestures I will explain here.
1. Remove the strap from the watch
Always. Cleaning a strap while it is mounted means risking wetting the case or forcing the lugs. Use a spring bar tool or your fingernails on those with quick release. If you have never removed a strap, come to the atelier the first time — I will show you how it is done in 30 seconds.
Place the strap on a clean, soft cloth. Set the watch on a separate cloth: never let solvents come into contact with the case.
2. Dust with a dry cloth
Before damp, there is dry. Pass a microfibre or light cotton cloth over the entire surface of the strap — front, back, edges, holes. The purpose is to remove dust and loose residue that, if dampened immediately, becomes mud that works its way into the pores of the leather.
For straps in cordovan or alligator, use only microfibre: cotton can leave microfibres on the scales.
3. Clean with a lightly damp cloth
Dampen a second cloth (not the dry one) with a few drops of lukewarm water — the cloth should be barely damp, never wet. Pass it with long movements along the length of the strap. Never circular movements: they ruin the grain of the leather.
If you have dried perspiration or light stains, a drop of neutral soap (liquid Marseille soap, unscented) on the cloth helps. Then rinse with a cloth using only water. No alcohol. No wet wipes. No shoe products.
4. Dry and let it breathe
Blot with a clean dry cloth. Do not rub. Then leave the strap in the open air, away from heat sources: no radiators, no direct sun, no hairdryer. The leather must dry at its own pace, 4-6 hours minimum. Forcing the drying hardens the leather and creates cracks in the months that follow.
Lay the strap flat, not rolled up. On a clean surface, preferably cotton or microfibre.
5. Nourish with a specific balm every 4-6 weeks
Once a month (every 4-6 weeks of daily wear), nourish the leather with a balm specific to fine leathers. For calf and goat: neutral beeswax balm. For alligator: balm specific to exotic leathers. For cordovan: neutral cordovan wax or nothing at all (cordovan nourishes itself over time).
Apply with a clean fingertip, in a small quantity (half a fingernail of product for the entire strap). Let it absorb for 30 minutes, then polish with a soft cloth. Say goodbye to animal fats, generic oils, undifferentiated “leather” products: every hide needs a dedicated nourishment.
6. Storage between one use and the next
If you do not wear the watch for a few days, store it laid flat in a case or in a drawer with low humidity (no bathroom, no kitchen). For daily wear, let it breathe at least one night a week: alternate two straps if possible. Leather that does not rest accumulates sweat and darkens unevenly.
When it is NO longer salvageable
Three signs indicate a strap beyond ordinary care: deep cracks in the folds (not superficial), detachment of the inner lining, persistent odour of mould or sweat that does not leave even after thorough cleaning. In those cases, the strap has had its time: bring it to the atelier for an evaluation (sometimes it can be recovered, sometimes it is best to replace it).
Cleaning a leather strap is less about technique and more about respect: understanding that leather lives, breathes, and responds to daily attentions. Five minutes a week of routine, and the strap will accompany you for years.
