As I knew the bracelet has screws, this was exactly why I ordered the best screwdrivers available before purchasing this watch.Citizen Grand Classic NB0040-58A
Caution! When removing links they are held in place with screws that have a 1 mm head and I stripped the head on one link during the sizing process. I have a 1 mm jeweler's screwdriver but perhaps not the highest quality. Before trying to size the bracelet, be sure that you have a high quality screwdriver of the correct size and that you have a device to hold the bracelet while removing the screw.
Altough I must say I didn't expect for it to have 1mm screws, but 1,6mm. But I ordered the 1mm screwdriver for fine regulating ETA movements anyway, so no harm done.
I have a lot of cheap screwdrivers, but they slip all the time, as they are too sharp, like on pic 3 here:
Maintenance and Repair of Watchmaker's Screwdrivers [11/2000] - TimeZone
These are the screwdrivers that I have on the way:
Horotec MSA 01.203-160 (1.6mm)
Horotec Ball Bearing Individual Screwdriver with Replacement Blades
Bergeon BERG-30080-16 (1.8mm)
Bergeon Intermediate Screwdriver Sizes
And also at Watchtool. But they are scammers, so I will have to open a Paypal dispute for a second time. I didn't order them at Ofrei, because I didn't knew if they come with spare blades.
But I see now that USD prices are a lot cheaper even with spare blades purchased separately.
Bergeon 6899 Ultimate - Bergeon Screwdriver 6899-AT-100 ?1.00mm = Black
Bergeon 6899 Ultimate - Bergeon Screwdriver 6899-AT-160 ?1.60mm = Violet
As for a device for holding the bracelet, I don't recommend one. I know for a fact that even plastic scratches polished bracelet sides.
I can do it in my hands just fine, even the ones that have two screws.
But I protect everything with electric tape now anyway, for example lugs when changing straps or bracelet sides when resizing. This is the only way to be sure you won't scratch anything. I used Scotch tape before, but spring bars tear even two pieces right away.
