Casio Duro MDV106 MDV107 Watch Band Adapters, 22mm to 20mm Stainless Steel Lug Converter, Silver Black Gold, Replacement Band Converter Set

CASIO DURO MDV-106 MDV-107 WATCH BAND ADAPTER
22mm to 20mm Stainless Steel Lug Converter

The Casio Duro is one of the most beloved affordable 
dive watches ever made. Its standard 22mm lug width 
means strap options are plentiful -- but sometimes 
you want to run a sleeker 20mm band for a more 
refined look. These precision machined stainless 
steel adapters make it happen perfectly.

Available in three finishes to match your Duro 
case -- brushed silver, matte black PVD, and gold 
tone. Choose the finish that disappears seamlessly 
into your watch for a clean factory-original look.

Set of 2 stainless steel adapters (one per side)
Spring bars included for installation
No permanent modification to your Duro
Complete kit -- nothing extra to buy

case while maintaining the iconic look of the watch.
