An annual-calendar chronograph with origins rooted in the Chesapeake Bay’s industrial heritage and style. The hand-guilloche dial with its wide array of cal.7751 complications is boldly presented through the tonneau-shaped case. A “screwpile” style of the timepiece’s case mimics the architectural inspiration taken from the Choptank River’s navigational beacons that rest along it. The instrument’s impressive durability and utility was designed for everyday wearers who want to be updated throughout the year. Complications include minute, hour, day, month, date, GMT, moonphase, and a chronograph that accounts for seconds, minutes and hours.

Our founders, Hartwig Balke and George Thomas made their first introduction to one-another on the Choptank river during simultaneous sailing tours of the Americas decades ago. One of the signature beacons shining light thankfully came to their rescue one foggy morning out in the bay. Together, they admired the copper-toned sunrise soon to arise as they comfortably sat in the beacons talking watches. The inspiration naturally came,  birthing the unique salmon-toned dial of the CT250-C and its beacon-style frame that would come years down the line and now available today.
