John Harrison developed the chronometer's mechanism, while the people who would use it at sea contributed practical design advice. Royal Navy officers and navigators discussed successive versions with him. A ship's master carpenter helped with the case and its construction. Warrant officers and other shipboard users could identify problems that a mechanism's designer would not necessarily encounter ashore. Their contributions helped make a precise clock into a workable navigational instrument.
