18K Minute Repeater with Perpetual Calendar

Excellent condition 18K hunter case minute repeater with perpetual calendar and moonphase.  The movement is signed by Samuel Lyon Jr., 57 Church Street, Blackpool, England.   The full plate movement is fully jeweled through the hammers with an English side lever escapement.  Movement, case and dial are all in excellent condition and all functions work correctly.  The massive 18K solid gold hunter case has no monograms or personal engravings.  The repeater slide is actually inset into the gold case band so only the operating edge of the slide shows, instead of the usual larger slide on other repeaters.  The perpetual calendar uses English language.
