Leather Strap Watch

Quick Release Bars, Explained

A quick release strap is held to the watch by spring bars with a small lever on the underside. Slide the lever toward the center of the strap with a fingernail and the bar retracts, freeing the strap from the case without a tool. Fitting a new strap is the reverse: seat one end of the bar in its hole, pull the lever, line up the other end and let go. The whole change takes under a minute, which makes a second strap an easy way to give one watch two different moods.

• A lever, not a tool. The spring bar retracts with a fingernail.
• Under a minute. Swapping straps is quick enough to do before dinner.
• One watch, two looks. A second strap changes the watch's character.

Finding the Right Hole

A watch strap should let one finger slide between the leather and the wrist, and no more. Too tight and the case presses on the wrist bone; too loose and the watch slides round until the dial faces the floor. Wrists swell slightly in heat and later in the day, so a fit that is snug at breakfast can feel tight by evening. If you land between two holes, use the looser one in summer and the tighter one in winter.

• One finger of room. The check that works for any strap.
• Larger wrist by evening. Leave room for heat and swelling.
• Between holes, go seasonal. Looser in summer, tighter in winter.

Breaking In and Caring for Leather

A new leather strap starts a little stiff and softens over the first couple of weeks as it bends to the wrist. Wearing it daily speeds that up, and so does flexing it by hand. After that, care is mostly about moisture. Take the watch off before washing dishes or showering, let a damp strap dry at room temperature rather than on a heater, and rotate between two straps in hot weather so each has a day to recover. A strap looked after this way darkens and softens rather than cracking.

• Stiff at first. Two weeks of wear shape the leather.
• Room temperature, not a heater. Direct heat cracks leather that air would have saved.
• Rotate in summer. Two straps let each dry between wears.

Black or Brown

Black leather is the more formal color and the easier to match, since it goes with black shoes, gray and navy suits and anything dark. Brown is warmer and more casual, and it makes the wood of the case part of one natural color story. Brown also shows its age more, darkening and taking on a patina over months of wear, while black stays largely unchanged. Dial color changes the pairing too; the black dial watch page shows how a dark face sits with each strap, and a strand from mens bracelets can repeat the leather's tone on the other wrist.

• Black for formal. Easy with dark shoes and suits.
• Brown for warmth. It ties the strap to the wood of the case.
• Brown shows patina. It darkens with wear while black holds steady.
