What is your favorite watch buckle / clasp?
Will the watch buckle / clasp affect your purchase decision?
With all the e-commerce channel, we can always purchase any watch buckle / clasp online if we don’t like the original buckle / clasp.
I would like to share my opinion on different watch buckle / clasp from my experience:
a) Pin buckle - The most common buckle for the watches, needs to insert the pin every time to wear the watch, but also can easily wear down the leather strap at the pin hole section. Normally I will purchase a clasp to replace pin buckle whenever is possible to increase the lifespan of my strap.

b) Butterfly clasp – Very convenience clasp and save my time to penetrate the leather pin hole, but need to tuck the extra portion of the strap into the loops. Besides, butterfly clasp required you to have correct strap length, otherwise, you will feel uncomfortable because it not positions at the center of your wrist.

c) Single-fold deployant clasp (out-fold) – It shares the characteristic of butterfly clasp and harder to position at the center of your wrist compare to butterfly clasp. Extra portion of the strap required to tuck into the loops.

d) Single-fold deployant clasp (in-fold) – Same function as above, but the extra portion of the strap is tucked inward.

Personally, I like in-fold deployant clasp because it saves my trouble to look for the pin hole and tuck the extra portion of the strap into loops (no bending or teardown anymore). Hence, it also improves the lifespan of my leather strap.
