バタフライウォッチデプロイメントクラスプ デプロイアントウォッチバックル交換用 レザーウォッチバンドストラップ, シルバー, 20mm, モダン

Excellent, looks good and comes with a complete set of spare bars and a tool for installation/removal

Good product bought my first one in 2022 / still holding up / reason for me buying again

Picked up a couple of these butterfly clasps in 20mm and 18mm for a Casio Pilot and a Sea-Gull 1963! Great fit after easy install and adjustment. Very pleased with the look, price and performance. Will update reliability after wearing it over time.

Fit, finish and overall craftsmanship are very good. Although it's larger than the simple buckle it replaces, there is no perceivable weight increase. The design engineering is also top-notch, and the color and other esthetics so closely match my original clasp that the only giveaway is that "Citizen" is not etched into it. This is the fourth clasp I've retrofitted to my watches and all have been different brands. This one is as good or better than any of the previous three, and at $10 it's a great value.

I tried this clasp on my timex week deer to add a bit more security to the strap. Personally, I found it ungodly uncomfortable on my wrist and thought it was a bit too thick for the band.
