Thanks to the Maritime Museum we now have the actual sounds made by made by H1's Grasshopper Escapement. All sounds, bells & ticks, are toggled on/off with the bell icon. Also now zooms higher resolution dials to full screen. Tap dials to zoom in/out. Version 1.5 added sound to the app, ticks and ship's bell including the dog watch and New Year's Eve bells. Toggle bells on/off by tapping the bell icon. Note: Ship's bell is not part of Harrison's H1, it's just an additional feature of the app. As early as the 15th Century a bell was used to sound the time on board a ship. The bell was rung every half hour of the 4 hour watch. A 24 hour day was divided into 6 4 hour watches, except the dog watch (16:00 - 20:00 hours) which could be divided into two, 2 hour watches to allow for the taking of the evening meal. The strikes of the bell do not accord to the number of the hour. Instead, on the 1st half hour of a watch 1 bell is struck, an additional strike is added each half-hour of a four-hour watch with eight bells signifying the end of one watch and beginning of the next. Bells would be struck in a pattern of pairs for easier counting, with any odd bells at the end of the sequence. After a mutiny on the Nore in 1797, British ships modified the bell system on the dog watch (16:00 - 18:00) so that the mutiny signal of 5 bells was never again struck. At midnight on New Year's Eve sixteen bells are struck - eight bells for the old year and eight bells for the new. Thanks for the feedback!
