Compare adjustment styles and fit options
Multi-hole adjustment: the multi-hole stainless steel milled clasp comes in 16mm, 18mm, 20mm and 22mm widths. On this particular listing, the 16mm version has five adjustment holes; the 18mm, 20mm and 22mm versions have six. Choose by the actual variant rather than assuming every width has the same hole count.
Watchdives short OTF option: the WDB002 short on-the-fly clasp has a listed length of 35mm and separate fit options for WD Speedy screw-pin bracelets, split-pin bracelets and other listed connections. Its length is not its attachment width. Read the end-link and fitment notes before choosing a version; one option does not fit every bracelet.
San Martin replacement option: check the San Martin 16mm fly-adjustable clasp against the bracelet you own. A matching brand name or nominal width alone is not enough to confirm a replacement will fit.
What to measure before replacing a clasp
Is clasp width the same as watch lug width?
Not necessarily. A bracelet or strap can taper between the watch and clasp. Check the connection at the clasp itself, including the end-link shape and the pin or screw dimensions specified for the selected product.
Are all adjustable clasps interchangeable?
No. Multi-hole and on-the-fly describe adjustment styles, not a universal mounting standard. Compare the exact attachment design, review the product's compatibility notes and check selected-variant availability. Contact customer service with your watch model and bracelet connection details when compatibility is uncertain.
