Piaget Adds Two New Perpetual Calendars To Their Polo Collection – Rose Gold & Obsidian

by Matt Clymo

Hot off the heels of their Perpetual Calendar Ultra-Thin in green, Piaget has released two new model variants at this year’s Watches and Wonders. A beautiful Rose Gold variant with the same striking green dial as their steel model, and another in White Gold with Obsidian dial, surrounded by blue sapphires.

Back in February, Piaget started the year off with a bang, and introduced their first Perpetual Calendar Ultra-Thin to the Polo line. In case you missed it, you can read about it here. Clearly they were on to a good thing, and for Watches and Wonders 2023 they’ve launched two brand new pieces, adding to the Perpetual Calendar Ultra-Thin Collection.

The first is a stunning rose gold variant with the same colour dial as the original Perpetual Calendar. Green and gold are always great colour combinations, and with the deep emerald green offsetting the rose gold, Piaget have created a beautiful contrasting case and dial. This is then offset by the same dark emerald green strap, in either Alligator or rubber, which can be swapped out via their quick change SingleTouch system.

Piaget have kept the same size and dimensions of the steel model – 42mm diameter and just 8.65mm thick with the same 1255P ultra-thin 4mm calibre inside. The movement powers all the complications on the dial, including the date, month (along with leap-year indication) and weekday along with the moon phase and leap year cycle with 42hr power reserve.

In addition to the Rose Gold, a third Perpetual Calendar Ultra-Thin model has been unveiled, and aligning it with their wider jewellery line, this model has on Obsidian dial and a blue sapphire set bezel in a white gold case.

Obsidian, which is a type of volcanic glass that occurs when Lava cools rapidly, isn’t quite a stone and not quite a mineral, and as a result, it can make for some stunning features in jewellery when cut specific ways. It also means that no dial is quite the same, meaning that the owner of the Piaget Perpetual Calendar Ultra-Thin in Obsidian will always have a unique piece.

Set into the white gold bezel are around 60 deep blue sapphires, set in a graduating formation that mirrors the lines from thicker to thin, depending on the position on them in relation to the dial and bezel. Whilst some people may not be a fan of gem set watches, I feel Piaget have done a good job here as the sapphires blend seamlessly into design, and are not too over the top for most tastes.

Again, Piaget have added both a rubber and Alligator strap in the same deep blue to compliment the dial and sapphires, which can be swapped out with the quick change SingleTouch system.

Both models are 30 meters / 3 bar water resistant, meaning they are fine for daily wear, however, even with the rubber strap, I’m not sure you’d want to do much water sports with these on. However, if you’re looking for a statement piece that is a little different from the norm, then either of these two model would be perfect for that.
