This is a universal stainless steel push‑button deployant clasp for watch bands, fitting strap widths from 9mm to 22mm. Crafted from high‑quality stainless steel with a precision polished finish, it opens by pressing the two side buttons and locks automatically when closed, offering comfortable wear and easy operation.
Material & Finish: High‑quality stainless steel (316L), finely polished – corrosion‑resistant and wear‑resistant.
Width adjustment: Adjustable via removable links or a sliding mechanism to fit strap tail widths from 9mm to 22mm.
Clasp type: Push‑button deployant clasp – opens by pressing side buttons, locks automatically when closed to prevent accidental opening.
Applications: Suitable for replacing worn clasps on leather, rubber, nylon or metal straps, or for custom strap builds.
Safety feature: Dual‑locking mechanism (main fold + push‑button safety) prevents accidental detachment during wear.
⚠️ Spring bar quality: The included spring bars (if any) may be basic; use original or high‑quality bars (e.g., Bergeon) to prevent detachment.
⚠️ Width matching: The clasp width must exactly match the strap tail width. Too tight may damage the strap; too loose may cause the clasp to detach.
⚠️ Button maintenance: Internal springs may fatigue over time. If the buttons lose return tension, replace the entire clasp.
⚠️ Water resistance: The clasp does not affect water resistance – no extra testing is needed.
⚠️ Cleaning: Avoid alcohol or abrasive cleaners that may damage the polished finish.
⚠️ Periodic check: Inspect spring bar tension and button function every six months to prevent accidental opening.
Q1: What is the difference between a push‑button deployant clasp and a pin buckle?
A: A pin buckle requires threading the strap through a frame and inserting the pin into a hole each time. A deployant clasp, once fitted, opens and closes with a button press – more convenient and reduces strap wear.
Q2: The clasp is loose at the strap connection after installation – what can I do?
A: The spring bar may be too thin or short. Try a thicker (e.g., 1.5mm or 1.8mm) or slightly longer spring bar. As a temporary fix, apply a tiny amount of clear nail polish inside the strap hole to increase friction.
Q3: The buttons do not spring back after pressing – what should I do?
A: The internal springs may be fatigued or rusty. Try applying a tiny drop of watch oil (e.g., Moebius 9010) and press the buttons several times. If still not returning, replace the clasp.
