Frequently asked questions

What is the lug width of the Kikuchi Nakagawa Murakumo MUR-001?

The Murakumo MUR-001 features a lug width of 22mm. This measurement should be verified in millimetres between the two internal attachment pins of the case. This is a deliberately undersized width compared to Western standards, a choice made intentionally by the Japanese manufacture to maintain specific design proportions.

Which strap do you recommend for the Murakumo MUR-001?

For the Murakumo, we recommend a leather strap in American alligator or vegetable-tanned calf, which dialogues elegantly with the case's satin finish. A grey taupe or dark brown calf confers minimalist sophistication. Alternatively, a cotton-blend NATO in satin weave for more casual wearings. Avoid high-gloss synthetic materials that would contrast too sharply with the watch's aesthetic philosophy.

How do you change the strap on the Murakumo MUR-001?

Strap replacement requires extraction of the spring bars from the lugs via 32 micro-slots on each side. Position the watch on a stable support, employ a dedicated spring bar removal tool, and push gently inward. After removing the worn strap, thread the new strap by first inserting it on one side, then aligning the strap holes with the lugs. Reinsert the spring bars at a 90-degree angle.

Can I use aftermarket straps on non-standard lug widths?

Yes, Milano Straps offers bespoke 22mm leather straps fully compatible with the Murakumo. The non-standard width is not a limitation; rather, it allows you to select made-to-order straps that amplify the elegance of the original design. Always verify the lug width before purchase to avoid incompatibility.

How long does a leather strap last on the MUR-001?

An alligator or vegetable-tanned calf strap on a watch worn daily typically lasts 3–5 years. Longevity depends on frequency of wear, ambient humidity, and periodic maintenance (cleaning, conditioning). A satin NATO strap is more durable, lasting 5–7 years. Replacement is straightforward and advisable every 2–3 years under intensive use.
