Replacement Transparent Sapphire Case Back Compatible with Rolex GMT-Master II 126710 , 126713 , 126719 , 126720

Showcase the craftsmanship of your watch’s automatic movement with this replacement transparent sapphire display case back, designed for compatibility with selected Rolex GMT-Master II 126710 , 126713 , 126719 , 126720.

The case-back housing is manufactured from corrosion-resistant 904L stainless steel and features a clear synthetic sapphire viewing window. This combination provides excellent durability, clarity, and resistance to everyday scratches while offering an unobstructed view of the movement.

This is a display-back conversion component and differs from the original solid case-back configuration. Compatibility may vary between reference variants, case versions, movements, and production years. Please confirm your complete watch reference, case dimensions, thread profile, movement clearance, and gasket requirements before ordering.

Professional installation is strongly recommended. Case-back security, movement clearance, and water resistance must be checked after installation. Water resistance is not guaranteed until the completed watch has passed appropriate pressure testing.

(Compatible third-party replacement part—not manufactured, sponsored, or endorsed by Rolex.)
