Care instruction

Our leather straps are made of all-natural vegetable tanned leather. There is no chemical coating or waxing on top, which is why they are so very soft and comfortable. This natural quality also causes aging of the leather by sunlight and everyday wear. Every strap gets its own individual patina, which is something we love. Please don’t treat the leather with oil or wax as it ruins the whole nature of the strap. This also comes with a warning: avoid direct contact with water, as it may cause stains. So don’t wear your strap in the shower or when swimming and be cautious of heavy rain or perspiration. We recommend not wearing the strap in the gym.

Installation advice

We advice using a high quality spring bar for installation of our straps. Especially with newer watches, the gap between the case or bezel and the spring bar may be more narrow than on older pieces. To avoid scratches on the leather, we advise you to treat the strap carefully and without force when installing it on your watch. If it does not seem to fit at all, you might need curved spring bars or a different watch strap altogether. If you're unsure about this, feel free to consult with us before placing your order.

Seems a bit loose? Here’s why

As vegetable tanned leather tends to shrink a bit when worn, all our leather watch straps are intentionally designed with a tiny bit more width to prevent them from feeling or looking too small after some wearing. When first installed with your watch, the strap might appear a bit snug – but after a while, it will stretch and fit perfectly between the lugs. For Bulang and Sons, this is a mark of quality and proof of our traditional and natural approach.
