Citizen Tsuyosa — strap questions
What strap size does the Tsuyosa take?
The Citizen Tsuyosa doesn't use standard spring-bar lugs — it has an integrated/proprietary fitting, so you need Tsuyosa-specific straps or an adapter kit rather than a normal strap.
Can I put a normal NATO or leather strap on it?
Not directly. A standard strap won't attach without a model-specific adapter — fit the adapter first, then a normal strap can be used.
Where can I buy straps that fit the Tsuyosa?
Search for straps and adapters made specifically for the Citizen Tsuyosa; generic sizes won't clip in without one.
