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.

Diablo black and Siena Tan NATO straps and carmel tan and black two-piece straps

I recently made two purchases from Bulag and sons. I purchased the Diablo black NATO and was thrilled with the quality. The leather is top notch and the burgundy highlights with black are unique.

I immediately made another order for the Siena tan NATO and the carmel tan and black two-piece strap. The leather used in all these products is beyond my expectations. It feels like fine Italian glove leather. I am particularly fond of the caramel leather two-piece strap that I was able to order in a long variety. It may be the most comfortable leather watch strap I own and I collect dozens of watches. It somehow manages to have a durable thickness that is seamlessly tapered, while remaining exceedingly soft and pliable, requiring no significant break-in period. The same applies to the leather NATOs and the black example.

I was, however, unable to employ the discount code despite sending an email and attempting to receive help. I spend a significant amount of money (over $700) and the code I was sent after signing up for the email miler just would not work so I abandoned the effort after two emails requiring assistance. This was disappointing.

Additionally, I would be interested in purchasing more straps, but your options for long two-piece leather straps were limited only to the black and light tan. The siena two piece darker tan was sold out in long. Having an 8 1/3 inch wrist I struggle to find watch straps that fit and was pleased to see you had some long options. I would like to see more of your selection offered in long. That all said, I couldn't be happier with the straps I received and I commend your artisan craftsmanship and plan to be a repeat customer.

Most Cordially,
