I was frustrated looking for a suitable springbar to swap leather strap in my Seiko SKX and 6309 diver watch. The Seiko’s Fat Springbar at 2.5mm diameter body is too fat for leather strap and other rubber/silicon strap ends. They are also very difficult to remove too ! During the search most thinner springbar are either 1.78mm body diameter with smaller ends ; which is of no good and will elongate the lug holes with prolong usage for these Seiko diver.
Found a source to custom made these 22mm springbar for Seiko Diver watch whom uses 22mm fat springbar with correct ends. These custom springbar are in 2mm body diameter and correct 1.2mm end tip. Double flange for easy removal and stronger than the generic 1.78mm type. Most important it will not damage lug holes on prolong usage too.
They are suitable for use in Seiko SKX, 6309 driver watch, Monster Tuna SRP639, Seiko SRP653 Scallop, Seiko Stargate SRP493 (Ver1 and 2), Seiko FrankenMonster SKZ255, Dagaz Tsunami.
