Here we present the full three-part series about the making of Derek Pratt’s John Harrison H4 reconstruction, originally written by Roger Stevenson, chief watchmaker at Frodsham.
Derek Pratt (1938 – 2009) was perhaps one of the most “complete” watchmakers of our time along with his friend George Daniels. The Swiss-based Englishman was firmly behind and part of many watches and projects that are today common knowledge, while his own name remains relatively hidden.
