Notes

One other pocket chronometer only, with tourbillon regulator, made by Guinand with the bridges in the form of his initials, is known to exist, No. 3321, it was made for the Spanish market and was fitted with a lever escapement. It was sold by Antiquorum in Hong Kong on 18 lune 1994, lot 298 of the catalogue. This one, with a pivoted detent escapement, appears to be unique.
