Following the preview of last December , at the Salon International de la Haute Horlogerie 2018 (Geneva, January 15-19) IWC completely unveiled the Jubilee Collection made to commend the significant milestone of 150 years of history.
Among the 27 restricted edition models from the Portugieser, Portofino, Pilot’s Watches and Da Vinci families, IWC likewise dispatched three restricted edition Tribute to Pallweber wristwatches with bouncing numerals.
This is the first occasion when that the Schaffhausen brand joins an advanced hours and minutes show in a wristwatch. IWC began utilizing this type of time show in pocket watches back in 1884 subsequent to tying down the rights to the presentation situation developed by the Salzburg watchmaker Joseph Pallweber.

Pretty revolutionary at that point, the historic Pallweber pocket watches showed the hours and minutes in huge numerals on pivoting circles.
However the innovative time show was in front of its age: the watches were just a commercial success for a short period prior to vanishing from the scene following a couple of years.

As a kind of perspective to the plan of the historic Pallweber watches and a tribute to F. A. Jones – the American watchmaker who established IWC – the windows of the computerized show are marked as “Hours” and “Minutes”.
A total of 775 watches will be delivered and, all the more exactly, 25 pieces dressed in platinum with white dial with lacquered finish, blue presentation circles, blued seconds hand (ref. IW505001), 250 of every 18-carat red gold with white dial with lacquered finish, white showcase plates, blued seconds hand (ref. IW505002), and 500 in stainless steel with blue dial with lacquered finish, white showcase circles, rhodium plated seconds hand (ref. IW505003). Costs are Euro 60,000, Euro 38,000 and Euro 24,000, in the request depicted.
Housed in the 45 mm case, the IWC-produced 94200 type beats at 28,800 vibrations each hour and ensures a force reserve of 60 hours.
While making this movement, the watch originators developed another answer for the in fact modern computerized show (patent forthcoming). While toothed gear-teeth moved the plates in the historic Pallweber pocket watches, the drive that advances the single-minute circle is currently provided by a different wheel train with its very own barrel. A delivery component that sets up an association with the watch’s primary wheel train opens the train every 60 seconds and afterward promptly bolts it once more.
Following 10 minutes, the single-minute plate moves the 10-minute circle forward by one position. Every 60th moment, the hour ring leaps to the following numeral. The way that the progression of force in the principle wheel train is uninfluenced by the different wheel train in the presentation circles ensures an exact rate and a high 60-hour power reserve.
Much the same as on the historic Pallweber pocket watches, the presentation plates are associated by a mechanical linkage with a star wheel (Maltese cross drive) and can be handily moved advances or in reverse utilizing the crown.
Delightfully completed and enhanced by a Jubilee emblem in 18-carat gold, the movement is visible through the sapphire-glass case back. iwc.com
