Ref. MM250-B2 | Series Two Mission Moon | Black Variant --- With this latest adoption of the Mission Moon Chronograph B, we present utilitarian intentions; implementing a brushed finish to the bezel and case for increased scratch resistance, custom molding the 42mm stainless steel case for better fit, and adding crown protectors. These attributes within our latest Mission Moon line only further ensure the +/-5 second accuracy of the proprietary ETA/Valjoux 7750 automatic movement while pushing the envelope in terms of contemporary design. These adjustments retain the elegant, confident, and explorative traits characteristic of our "Mission Collection" while bolstering the practicality for which this timepiece was intended to service for, space travel and adventure beyond the bounds of comfort. Limited to 100.

History The first ever Towson Watch Company timepiece, the Mission Chronograph was designed and built in 2000 for an astronaut on a NASA STS-99 mission, which mapped the earth’s surface from the south of Greenland to the northern edge of the Antarctic. The first line of Mission Chronographs built were tested and proven in space, serving as faithful companions to the astronauts on-board the Endeavor aircraft.
