For those of you who are familiar with regulators, you know that they belong in workshops instead of wrists. This is because regulator display are used as a basis for adjusting timepieces that are being worked on by master watchmakers who need high precision. These regulators uses the main display (main hand) for the minutes hand and sub-dials for the hours and seconds. Patek has adapted this type of display for their 5235 released back in 2011. The 5235 as we know it was a remarkable timepiece with new tech built in to it such as using Silinvar components that are not only anti-magnetic and durable but also need no lubrication. The 5235 also brought in an annual calendar.
Moving on to the new Patek Philippe Annual Calendar Regulator 5235R, it is now presented in rose gold. This is a smallish watch at just 40.5mm by 10mm dimensions, pretty thin actually for a complex timepiece. Meanwhile, the polished and satin finish of the case look great and just perfect for dressy occasions, after all, rose gold is a warm color. I like the design of the case as it has that premium feel to it.
As for the dial, well to be honest I am a bit confused as it does not look very clean, maybe because of the choice of contrasting colors. A warmer case for me could have been complimented by softer ones on the dial, but no, there is a graphite colored base instead with brushed finish. The peripheral minute track is also in black as well as the sub-dials. Nevertheless, the white colored hands and inscriptions somehow fixes this confusing contrast, it actually looks sharper if you ask me.
As for power, it comes from a self-winding Calibre 31–260 REG QA developed in-house and certified by the Patek Philippe Seal. It features better chronometry since Patek uses only stable portion of the power reserve which is maxed out at 48 hours.
Finally, the new Patek Philippe Annual Calendar Regulator 5235R wears on a nice matte black alligator strap.
