One of the pleasures of horology is the appreciation of the engineering works behind the mechanical wonders, one of which is the striking mechanism found in minute repeaters.
In the video above, Michael Manjos of Betteridge demonstrates how one such pocket watch minute repeater made in the 1800s and from Patek Philippe works.
In the example, after activating the pusher at the side of the case, the chiming mechanism strikes the time of 3.49 by way of three “dings” (to sound 3 o’clock), six “ding-dangs” (for three quarters, each quarter indicated by a “ding-dang”) and four “dings” (to sound 4 minutes). Add these up and one will know the time is 3.49.
While the principle of chiming the time remains unchanged, modern minute repeaters, especially those from Patek Philippe now sound much more refined and rhythmic.
The Patek Philippe pocket watch shown was a bespoke piece as it has an elaborate decoration on its case, indicating that meant that it was made for royalty or nobility.
Though the inner case of the pocket watch indicates the number 90913, Manjos highlights that this Patek Philippe pocket watch does not have a reference number as the numeral referencing system only began in 1932 (with the Calatrava Reference 96 of 1932).
