Jaeger-LeCoultre Reinterpret The Master Ultra Thin Power Reserve

The Jaeger-LeCoultre Master Ultra Thin Power Reserve has received a sophisticated aesthetic update and a gradient blue dial.

The Master Ultra Thin collection epitomises Jaeger-LeCoultre’s philosophy of watchmaking, uniting timeless beauty with mechanical virtuosity to create the quintessential dress watch. The new-generation Jaeger-LeCoultre Calibre 938 provides a 70-Hour Power Reserve.

In line with La Grande Maison’s pursuit of timekeeping precision, together with added utility for the user, the Manufacture constantly improves its in-house calibres in line with advancing technology. Calibre 938 (below) has been significantly revised to power a new generation of timepieces. Most notably, the power reserve has been increased to 70 hours – long enough to leave the watch aside for an entire weekend and wear it again on Monday with no need to rewind it or reset the time. 

While the size of the case remains the same as the preceding version of the Master Ultra Thin Power Reserve – retaining the elegant 39mm diameter and 8.95mm thickness – its design has been subtly modernised, with revised proportions and slimmer, more elongated lugs that make it even more comfortable on the wrist. 

The dial architecture has also been refined. While retaining all the symmetry and balance of the earlier dial layout, larger sub-dials highlight the complications, making the date, power reserve and small seconds displays even more legible than before, while giving the dial a more integrated overall appearance. This is amplified by the newly elongated shape of the applied hour markers, and the use of a different finish (polished and satin) on each facet of the Dauphine hands, and the use of transferred golden dots to mark the minutes track. 

Adding a final flourish, the new Master Ultra Thin Power Reserve is presented on a navy-blue alligator strap. Straps and buckles can be very easily interchanged as the wearer wishes – adding even more versatility to this sophisticated, modern timepiece.
