explorer 1 224270

Im looking for a VSF explorer 1 224270. No TD's seem to have them in stock atm but i can pre order through andiot.

My question is, why are the clasps different on andiots website to trusty time website?

Trusty time advertise - Rolesor Flip Lock Clasp
Andiot advertise - deployant clasp

What is the difference and why are they different when both should be from the same factory.
