If it gets wet, gently wipe with a soft cloth and let it air-dry naturally. Do not use a hairdryer or expose it to heat/flame. Avoid over-conditioning: Barenia only needs a very small amount of leather cream, applied lightly after long-term use. With Barenia, minor scratches tend to soften over time and become part of its natural patina. 3) Warranty policy 6-month warranty for issues related to glue/adhesive and stitching. Not covered: damage caused by user wear or misuse, such as water absorption, scuffs, scratches from normal use, etc. 4) Notes If you need a size/length different from the standard, please contact us for made-to-order customization. Watch photos are for illustration only; the watch is not included with the strap. 5) The story of Barenia calf leather Barenia is a “leather legend” rooted in Hermès’ saddle-making tradition—originally developed for equestrian use, where it had to be both durable and elegant. The story is often linked to Alsace, France, home to long-established tanneries, with names like Tanneries Haas frequently mentioned. Some even associate the name “Barenia” with the nearby area of Barr. What gives Barenia its unmistakable character is its special tanning process: it is double-tanned (a combination of chrome tanning and vegetable tanning/dyeing), then heavily nourished in oils for weeks. This creates exceptional durability and a famously beautiful patina—time’s own color layer—forming gradually through wear.
