Patek Philippe Gondolo 8 Days, Day & Date Indication

Baselworld 2013…

Patek Gondolo 8 Days with Silvery Dial Ref 5200G-010 White Gold Patek Gondolo 8 Days Day Date  5200G-001 Blue Dial

Overall this year Patek does not have many “new new” models, instead it seems they have focused on offering existing models in new case metals, and some other smaller details, such as minor case changes and also dials.  Though some of these will be meaningful changes for Patek collectors — for example the Ref 5170 two-register chronograph is now offered in white gold with silvery-white dial and a full Breguet numeral layout.  This is significant because the prior model had two roman numerals XII and VI and stick baton hour markers.  Being a fan of Breguet numerals, I really like the new style of the 5170 — but I digress — more on this later.

Patek Philippe’s new Ref. 5200 Gondolo 8 Days, Day & Date is offered in sunburst blue and silvery white versions.  It is set in a contoured, rectangular Art Deco case with two tiered sides, and a newly developed, manually wound form movement with silicon components. Case dimensions are 37.4mm × 46.9mm x 10.4mm thick.

The dial features an 8-day power- reserve display in the upper half as well as the date by hand, the large day-of-week aperture, and the subsidiary seconds dial in the bottom half.

The new caliber 28-20 REC 8J PS IRM C J form movement was inspired by the Ref. 5100 “10-Day” first presented in the year 2000.   Insiders will no doubt remember the Patek Philippe “10-Day” which had its debut in the year 2000 and delivered power for two additional days. The fact that the Ref. 5200 falls short by two days is due to the date indication and the day aperture which require more energy.

The new Caliber runs at 4Hz (28,800) and features twin in-line barrels which still guaranteed power for at least 192 hours.   The instantaneously switching calendar (date and day indications advance simultaneously at midnight within 3 milliseconds) is another noteworthy feature.   As I alluded to above, it uses silicon components as we have seen before from Patek — Spiromax® balance spring and a Pulsomax® lever and escape wheel.   You can easily identify these components as they have a light blue shimmering look (bottom right, below):
