Notes
“Deck-Watch”
A “deck-watch” is a precision watch used on the deck of boats for navigational purposes (point reading) to avoid disturbing the proper functioning of the marine chronometer, which remains in a specific area of the ship (chronometer room or captain’s cabin).
For more information on this type of time-keeper, now a collector’s item, see Norbert Eder’s reference book.

Guillaume Balance
The Guillaume balance is a compensated bimetallic balance, made of anibal (an alloy of steel and nickel) and brass, after the works of Dr Charles-Edouard Guillaume (1861-1938), with which the middle-temperature error is practically eliminated.
The middle-temperature error (or Dent’s anomaly), is the difference between the rate of a chronometer at the mean temperature and the average of the rates at extreme temperatures.
This type of balance was used by the horological manufactories since 1904.
