Frequently asked questions

What is the lug width of the Kikuchi Nakagawa Ichimonji ICH-002?

The lug width of the Ichimonji ICH-002 is precisely 20.00 mm. This measurement is specific to this model and ensures perfect proportions between the 36.80 mm case diameter and the strap. It is essential to use 20 mm straps to maintain the design harmony and proper articulation of the watch on the wrist.

Which strap is recommended for the Kikuchi Nakagawa Ichimonji ICH-002?

For the ICH-002, we recommend three categories: alligator leather in black or deep brown for formal contexts, vegetable-tanned calf leather for those who appreciate patina evolution over time, and NATO straps in nylon or FKM rubber for everyday casual use. Your choice should reflect your lifestyle and the dial tone of your watch.

How do I change the strap on the Kikuchi Nakagawa Ichimonji ICH-002?

The ICH-002 uses standard spring bar lugs. To change the strap: 1) position the watch face-down on a soft surface, 2) use a spring bar removal tool to gently compress the attachment spring, 3) slide the old strap away carefully, 4) insert the new strap by aligning the end with the lug and release the spring. Avoid excessive bending of the springs.

Can I use aftermarket straps on this model?

Yes, the ICH-002 is compatible with universal 20 mm aftermarket straps. However, we recommend choosing high-quality materials—vegetable-tanned leather, woven NATO Zulu straps, or FKM rubber—to maintain the sophisticated aesthetic of the watch. On milanostraps.it you will find a selection of verified 20 mm straps ready to use.

How long does a leather strap last on the Kikuchi Nakagawa Ichimonji ICH-002?

Durability depends on the material and maintenance. A vegetable-tanned calf strap lasts approximately 2-4 years with daily wear. Alligator leather, being more robust, can reach 4-6 years. To extend strap life: avoid prolonged direct moisture exposure, pat dry gently after accidental water contact, and periodically apply a specialist leather conditioner. The strap naturally evolves, developing patina and character.
