The Sea & Sea Motormarine MX 10 is an underwater 35mm film compact built for amphibious use without a separate housing. It belongs to Sea & Sea's Motormarine line of dive-oriented cameras and was sold as an entry-level option for divers and snorkellers.

Evidence of what a Motormarine MX 10 is worth at UK auction is thin: the only hammer result on file is £31 from March 2023, a wholesale saleroom price that excludes commissions. On that single data point the camera sells for low double-digit figures today, though one record is not enough to define a reliable price range and condition, completeness of seals, and inclusion of the dedicated flash will all move the value.
