The TB88's hand-wound movement unites all the technical and aesthetic characteristics of a classical Arnold chronometer. The letters "'TB" stand for true beat, a complication that permits the precision timekeeping required for navigation at sea. Unlike a conventional mechanical escapement, a true beat escapement has an unusual single-pallet design that measures out time in complete one-second steps rather than the fractions determined by the balance frequency.
