Choptank integrates a triple‑calendar chronograph within a 39 mm tonneau‑shaped stainless steel case. The calibre is a modified Valjoux 7751 automatic movement, regulated by Towson watchmakers and fitted with hand‑finished bridges. The salmon guilloché dial displays day, date, month and moonphase indications alongside 12‑hour chronograph counters, protected by a sapphire crystal. Each case is machined and finished in Maryland, numbered and engraved, with a lifetime warranty for the original owner. Production of this reference has concluded, and remaining examples are offered from archive stock.
