I thought I would pass along some not so well known tip on changing your strap on your Panerai deployment.
This should take you about a minute. You will need some scotch tape or blue painters tape. Just dont use Duck, Electrical or Gorilla tape.
The idea is to apply a tape tale about 1" to use as a guide to thread either a leather or rubber strap through the deployment buckle.
Remove 3" of tape and wrap it around the end of your strap leaving a 1" tail of tape.
Slide tail of tape through the deployment buckle.
You must pull the tape tail while pushing the strap up and over.
The tape should help the tiger teeth of the buckle slide easily up and over the strap. You need to slightly bend the strap as you feed it through the deployment buckle.
