Replacement Case Back Screws Compatible with Omega Constellation 27mm

Restore a secure and properly aligned case back with these replacement case-back screws, designed for selected Omega Constellation 27mm watches.

Each screw features a 1.5mm head, 2.6mm length, and 1.0mm thread size. Manufactured for accurate fitment, these screws help fasten the case back securely to the watch case when installed correctly. They are suitable for replacing lost, stripped, corroded, bent, worn, or damaged screws during professional watch servicing or restoration.

Compatibility may vary between complete watch references, case materials, case-back designs, and production versions. Please confirm your full watch reference and compare the screw dimensions, thread pitch, head profile, and finish with the original components before ordering.

Professional installation is strongly recommended. Screws should be tightened evenly to the appropriate specification to prevent damage to the threads, case back, or watch case. Water resistance is not guaranteed until the completed watch has passed appropriate pressure testing.

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