The Fitwell M3 Keeperless Stainless Steel allows easy micro-adjustment of your existing watch straps. It is designed to allow the tail of your strap to fit underneath the buckle side of the strap so that keepers are no longer needed, though it can be used as a long traditional buckle as well (with keepers).
If you find that you are often stuck between sizes on your watch straps, or want an easy way to make small adjustments in warmer or cooler weather, Fitwell Buckles are the answer. They double the number of hole positions available and allow you to adjust your strap size in between the standard holes.
Compatible with most watch straps, with or without keepers

A note aboutbuckle size:
Fornon-tapered(straight) watch straps, select the Fitwell buckle size that corresponds with your strap width. Fortaperedstraps, we recommend measuring your existing buckle width inside the buckle, or the strap itself where the buckle attaches, and choosing the Fitwell buckle size that matches. Typically tapered straps measure 2mm - 4mm narrower at the buckle than at the lugs. For example, if your 20mm strap (at the lugs) tapers to 16mm at the buckle, a 16mm Fitwell buckle would be the correct size.
