Price is for 2 pairs (4 pieces) of custom springbar !
Singapore Seller, Fast Shipment and Ready Stock !

There have been many request from customer for custom springbar for the Seiko Monster, Sumo and MM300 (all having 20mm lug) for mounting on mesh bracelet, leather strap and aftermarket rubber strap. Seiko usually make their 20mm lug diver watches with drilled-thru holes and are great for easy the fat springbar removal ; as oppose to some of their 22mm lug diver watches with no drilled-thru lug (which can be a challenge to remove these fat springbar !).

These custom 20mm springbar are suitable for all Seiko Monster (verI and VerII), Sumo, MM300 (or any 20mm drilled-thru lug diver watches). They are custom made for mesh bracelet but will also fit into leather strap without stretching the leather.

*These custom 20mm springbar are flangeless, they are recommended only for drilled-thru lug watches.

**It will be nightmare to remove them if there is no drilled-thru lug ! Please take note.

Please avoid installing generic 1.78mm diameter springbar with 0.7/0.8mm pin head, as it may wear out the lug holes on prolong usage.
