Railroad time, worn on the wrist
The POTOMAC is named for the river and drawn from the American railroad pocket watch. Towson's workshop stood beside the B&O Warehouse in Baltimore, home of the Baltimore & Ohio, the nation's first common-carrier railroad.
Rail workers could not reach into a pocket to check the time, so the pocket watch moved to the wrist. Hartwig Balke wanted the POTOMAC to carry that step: a 42 mm polished case, small seconds at six, and numerals he took from an American pocket-watch dial.
Inside is the Unitas 6498, a hand-wound caliber first made for pocket watches. George Thomas and his apprentices built about 1,000 of them between 2005 and 2015, each one decorated, oiled and regulated to his standard. You wind it in the morning and watch it run through the sapphire back.
