I acquired a mid 70's zenith with NSA band a few months back. Mine had all the links on the bracelet so I found it too loose and wanted to remove a few. I purchased the Bergeon 6744 Watch Bracelet Pin Remover - HB6744 and a Bergeon 1447 Boxwood Mallet - HM1447. As LouS says the NSA bracelet requires a lot of force to push one of the pins. Maybe a metal mallet would have been better than the wooden one I've got. I soon gave up in fear of damaging the bracelet and instead took it to a department store watch repairer. I watched as he used a metal mallet with reasonable force and then also had to use pliers to pull out the pin as the pins on the tool aren't long enough to fully force out the pins in the bracelet.
Since then I've been able to use the Bergeon kit to remove pins from other bracelets, just not the NSA!
