I was thinking of changing the titanium bracelet for a strap for a few weeks and swap back and forth whenever suited on my Zenith Defy El Primero 21( skeleton ) however i wanted a genuine strap and contacted Zenith. They said they will sell me the strap but i would need to send my watch to them to swap as its a “ specialist” job to change. This is added time and cost and has put me off a bit. So why is it only a specialist job? Cheers.
I can't see why out needs anything other than spring bar tweezers.
