The Button-Stud Band in Black Chromexcel leather by Form Function Form does away with any type of buckle or clasp, and instead has a single, stainless steel stud that holds the long, leather band in place.

Each strap is laser-cut, hand-burnished and stitched from fine leather sourced from the 100-year-old Horween Leather Company in Chicago. Click-in adapters in stainless, silver, space gray and space black are sewn into the two-piece strap. The button-stud closure is either stainless or black stainless, depending on which adapter color is chosen. 

Echoing the individuality of Apple Watch, Form Function Form takes customization to new levels in the design of its one-of-a-kind Button-Stud Apple Watch Band. This ingenious leather strap has 21 different size options, and comes with a lifetime warranty.

Determining the perfect size is easy. Get ahold of a rubber Apple Sport Band, and figure out which fits your wrist: S/M, M/L or XL. Next, pick the hole number from 1 to 7 on the Apple Sport Band (1 being the tightest hole and 7, the largest). When you place an order for, say, a M/L 6 Button-Stud Band, it will be custom-made to these specs.

Please do not guess or attempt to adjust your size to account for the stretch of the leather or whether you think the leather should be tighter or looser.  We will absolutely adjust your size to get you a perfect fit, but begin with ordering the size you actually wear; we’ve attempted to accommodate stretch and how a leather band needs to be worn already in our sizing, so if you ‘double-up’ on these adjustments, it is highly unlikely you’ll end up with a band that fits you.

A note about the new Apple Watch sizes: All of our bands will fit the new, larger Apple Watches. If you have the new 44mm Apple Watch, it’ll work with the old 42mm straps. And the new 40mm Apple Watch works with the old 38mm straps.
