Strap for Urho Chrono Black

The lug width of the Leijona Heritage Urho 19.100.01.210 is 22 millimetres. This measurement is taken by positioning a digital calliper between the two spring bar pins that hold the strap to the case. All straps specifically dimensioned for this lug width are compatible with this model.

The choice of strap depends on intended use and personal aesthetic preference. For a versatile and timeless configuration, a vegetable-tanned calf leather strap in tobacco or brown is recommended: this material ages gracefully and aligns with the brand's Nordic design philosophy. For formal contexts, a polished black alligator strap complements the stainless steel case elegantly. For technical and sporty applications, a NATO fabric strap maintains the sober visual language of the piece.

The strap is changed using a spring bar tool. Position the tool underneath the lug pin, apply gentle pressure to release the internal spring, and extract the bar from the case. Repeat on the opposite side. Next, insert the new strap by threading one spring bar into the case first, followed by the other, ensuring that the internal springs lock correctly. The entire operation takes minutes and requires no special expertise.

Yes, the Leijona Heritage Urho 19.100.01.210 is fully compatible with artisanal aftermarket straps. Any strap made for the 22-millimetre lug width fits the case perfectly. Numerous options are available in leather (calf, alligator, shell cordovan), NATO fabric, technical rubber and other materials, allowing customisation in both colour tone and overall aesthetic character of the watch.

The lifespan of a leather strap depends on the tanning method, material quality and intensity of use. Vegetable-tanned calf typically lasts 3-5 years with moderate daily wear. Alligator, being more robust with denser fibre structure, may last 5-7 years. In conditions of intensive use or frequent exposure to adverse weather or water contact, durability may be reduced. Vegetable tanning has the advantage of visibly ageing, documenting wear through patina and tonal shifts: many enthusiasts appreciate this evolution as part of the ownership experience.
