It differs from porcelain enamel in the way it’s polished after firing. These dials are meticulously crafted by specialist manufacturer Ando Cloisonne in Nagoya, where craftsman Wataru Totani paints the glaze by hand onto the surface of the dial (worth noting is that he uses a lead-free glaze specially developed for use in these watches). The dial is then fired at 800 degrees Celsius. This process is repeated several times to ensure the evenness of the enamel.

Reference SPB073 uses Seiko’s 6R27 caliber, which beats at 28,800 bph and boasts 45 hours of power reserve. This movement includes a calendar sub-dial at six o’clock and a power reserve indicator at nine. The second of the pair, the SPB075, runs the well-known 6R15 movement with a slightly lower 21,600 bph and 50 hours of power reserve.Both mo...
