While the
5930G harks back to this much admired reference, its execution is decidedly modern. Beneath its beveled sapphire crystal, the blue dial is hand-guilloched in a circular pattern, contrasted by luminous-filled, applied white-gold indexes. The reference is also classically sized, at 39.5mm in case diameter and only 12.86mm thick, making it the world's smallest and thinnest world-time chronograph. A nod to its inspired design, the case of the
5930 further features ‘winglet’ style lugs and various brushed and polished finishes across the case.
As with other world-time displays from
Patek Philippe, the function is activated via a pusher at 10 o'clock on the case. The time zone is displayed at 12 o'clock and advanced with each operation. While changing time zone, the hour hand is completely disengaged from the movement, so neither the amplitude, nor the steady progression of the minute hand are affected. The chronograph hand also continues unstirred.
Combining a time display (in 24 different timezones) and 30-minute flyback chronograph within the same watch, is no small feat.
Patek Philippe achieved this through their caliber CH 28-520 HU - referred to as entirely-new, owing to the various modifications and new parts required, compared with existing calibres. Given the absence of a running seconds hand, the calibre was also developed to keep the chronograph-seconds hand running at all times, maintaining legibility. The calibre features a large, four-spoke
Gyromax balance-wheel, with four poising weights, beating at a frequency of 4 Hz (28,800 A/h), with a guaranteed power reserve of 55 hours (50, with an activated chronograph).
As with all contemporary
Patek Philippe watches, it has the
Patek Philippe seal, guaranteeing its accuracy to -3 and +2 seconds daily, keeping time better than the industry benchmark chronometer grade movements. The movement is beautifully finished, with exquisite chamfering on all angles, polishing and decoration, in the form of Geneva striping.
This example comes as a full-set, with its original
Patek Philippe, dark-blue alligator strap, corresponding
Patek Philippe white-gold deployant clasp, as well as its accompanying box and original paperwork.
Viewings can be arranged in Central London by appointment.
