Ref. MM250-2-BR was designed, handcrafted, and recommended by the master watchmaker himself - Hartwig Balke. This custom reference variant of the Mission Moon | Series Two features our founder’s signature "black rhodium" composition. The opulent presence on the wrist and consistent pairing of elements on the dial gives to clear readability and precise measurements in all light conditions. Hartwig Balke remastered the 7751 movement caliber to achieve chronometer-grade accuracy and allow for simplified operation of the day, date, month, 24-hour, 12-hour, moonphase, and chronograph counting functions. Assembled, decorated, and calibrated in-house by Towson watchmakers.

Assembled and decorated in-house in Baltimore, MD. The guilloche dial vests a moonphase window, date-calendar, hour/minute counter sub-dials, day/ month windows, tachymeter, and a 24-hour scale.
