Blue calendar dial, rose-gold-tone bracelet
BBSF's clone Caliber 5134 operates the day, date, month, leap-year and moonphase indications. The calendar requires manual correction at the end of shorter months, so it is best treated as a functional multi-calendar rather than an unattended perpetual memory. The case measures 41mm across and 11.4mm thick, with an integrated plated bracelet and folding clasp.
