Strap for Boulton Mechanical Stainless Steel / Green

The lug width of the Hamilton Boulton H13519561 is 22 millimetres. This measurement represents the available space between the two pins that attach the strap to the watch case. You can verify compatibility by measuring the distance between the attachment points directly on your watch.

We recommend alligator straps with vegetable tanning (cognac or burgundy tones) to maximise harmony with the Art Deco design. Alternatively, calf leather with medium grain texture offers contemporary sobriety. For daily wear, canvas NATO or vulcanised rubber straps maintain practicality without aesthetic compromise.

Strap replacement requires minimal tools: a spring bar tool specifically designed for watches. Insert the tool into the lateral slot of the strap spring, gently compress the metal pin and slide out the old strap. Insert the new strap by aligning the pins with the slots, release the spring and verify engagement. If uncertain, consult a professional watchmaker.

Yes, any strap with a 22mm lug width is compatible with the Boulton. However, we recommend evaluating the aesthetic pairing: the elongated rectangular case harmonises better with proportionate strap widths. Straps that are too robust may unbalance the model's proportions.

Durability depends on leather quality and daily use. An alligator or vegetable-tanned calf strap, with proper care (avoiding prolonged immersion and excessive humidity), maintains structural integrity for 3-5 years. Leather develops patina and character over time, acquiring aesthetic merit. Vulcanised rubber straps have superior durability (5-7 years) if not exposed to intense prolonged sunlight.
