    HMT Jawan movement specs

    How many beats per hour for the HMT Jawan and how long is the power reserve? Are all hand winding HMT watches (particularly the Pilot and Sona) the same movement?

    Thanks

    All I can say is that if it's the movement based on the ETA 1080, it should be 18000 A/h (2.5Hz).

    I understand the movement is based on the Miyota 0201 movement which is also 18000.
    Atleast if the Jawan is a Handwinder.
    I think all HMT mechanical movement are based off Miyota movements, but not sure.

    As has been mentioned, the beat rate is 18000bph. In good nick the power reserve is about 43 hours. All gents hand wind HMTs had the same movement. There also was an open heart and a date version of this movement.

    Kind regards
