20mm Black PVD Plated Stainless Steel Butterfly Deployment Buckle Clasp BKL150A

Bought this for my Hamilton khaki navy scuba. I really wanted a deploment clasp to make it easier to slip on and off. The deployment part works well. It very sturdy and secure. My issue is the edges on the release buttons are very cornered instead of rounded. Almost torturous. I sloved this by using a diamond sharping set to round and smooth them out. Without modification its almost unwearable

Hadley Roma is the Cadillac of deployant clasps. Great product. Not the cheapest price, if that is what you are looking for.

I bought this for my Casio G-Shock MTG910 that I put a GW-500A resin band on. It looks great since the black metal blends perfectly with the black band and is very comfortable. It also stays locked on my wrist and secures my watch much better than the regular clasp. I bought a Modena butterfly clasp prior to this that is shiny and it would pinch my skin. Not the Hadley-Roma...this is not noticeable to the wearer and that's what you want. The only thing I had to do to get this to fit my Casio band was to use a little sandpaper on the small area of the band (both sides of the clasp end) 0.5 mm on each side where the clasp goes so the spring bar catches in the butterfly clasp and the 21 mm band end becomes 20 mm.I posted 5 pictures of this clasp on my watch so you can see how it looks on a black watchband.I just wish butterfly clasps had that regular bracelet bands have are micro-adjustments. I haven't seen this with any butterfly clasp manufacturer. Maybe Hadley-Roma can pioneer this!
