FITMENT NOTES
Watch references and applications supplied by the merchant, not independently verified factory matches. Check actual 21mm lug spacing, spring-bar specification, hole position and case clearance on the exact watch. Confirm deployant-specific tail compatibility with the 18mm clasp. This is not the older 20mm pin-buckle strap ZSZ000008. Shared nominal width alone does not guarantee compatibility or a factory-approved conversion.
EXCLUSIONS
Other lug widths, incompatible integrated connectors, insufficient case clearance or incompatible pin-buckle strap tails.
