A triple calendar moonphase chronograph with origins rooted in the Chesapeake Bay’s industrial heritage. The Choptank E250 packs the functions of a high-grade tool-watch into a uniquely-crafted work of horological art. The dial's blossoming hand-turned guilloche is formally complemented with rhodium hour-markers and three engine-turned sub-dials, available in your choice of silver or copper. A sapphire crystal exhibition case-back reveals the 7751 Swiss movement that has been assembled and decorated in-house in Baltimore, MD. The instrument’s impressive durability and utility was designed for everyday wearers who want to be updated throughout the year. Complications include day, month, date, moonphase, 24-hour, and a chronograph that accounts for seconds, minutes and hours.

The Choptank E250 triple calendar chronograph drew inspiration from the Chesapeake Bay’s industrial heritage and style. The beacons shining light through the Choptank River, installed during America’s industrial boom, stand today as sentinels of maritime history in the Chesapeake region. They guide schooners, skipjacks, and steamboats through shallow waters at night. Our watchmakers wanted to translate the presence and utility of these beacons into a horological form with the Choptank timepiece.

Exploring the bounds of shape in watchmaking design was the primary purpose of our nautically-inspired project. The Choptank’s case shares an industrial “screwpile-style” reminiscent of the iconic Chesapeake Bay beacons. Aesthetically, the shape of the lighthouses were always an eye-catcher for sailors, even more so than their shining light. Their attractiveness and utility aligned. The shape of the structure was designed precisely for visibility and comfort, reflecting light in dozens of directions with an array of surfaces that produced a bulging yet homely effect. 

Hartwig sketched the shape onto his sketch pad from the bow of his boat one morning, rounded the corners and flattened its ends while maintaining the beacon’s general design. After a few refinements, his prototype sketch of the Choptank’s case was complete. To honor the instrumental value these beacons carried for Hartwig and fellow sailors alike, our Choptank had to serve as a sufficient tool-watch. It was only necessary to use the 7751 and make it an annual-calendar moonphase chronograph. We chose this movement to bring the story to life, and have the Choptank aesthetically and functionally replicate the value of the river beacons. Giving sailors the maximum utility mechanical horology has to offer in one uniquely elegant instrument.
