I bought this for a Seiko dive watch that was only available with a rubber diver watch band, the orange dial solar dive watch.  A well machined and finished solid machined link band designed to be used with Seiko 2.5mm diameter spring bars.  A set of those are included with the band.  The spring bars may not work with other watches that do not have fully drilled through band mounting lugs.  Strapcode does offer 20mm long 2.5mm diameter spring bars to fit normal watch lugs.  The Strapcode spring bars are offered in the Amazon "Everything Else" area.

Major adjusting length by removing links is more of a PITA than it could be due to Seiko using their pin and collar connecting pins system.  IMO this is needlessly complex.
