Orient F7F44

The Orient caliber F7F44 is an in-house automatic movement with hand-winding capability, manufactured in Japan. It operates at a frequency of 21,600 vibrations per hour and delivers a 50-hour power reserve, featuring a power reserve indicator and small seconds complication. The movement incorporates Diashock shock protection and Orient's Magic Lever winding system, with a skeletonized balance wheel creating the signature "open heart" display. Finished with Geneva stripes and chamfering, it is visible through a sapphire crystal case back. The caliber is currently in production, powering the M34 F7 Semi Skeleton watches in Orient's M Collection, introduced in September 2024.
