For high horology, Carl F. Bucherer is chief among the brands associated with Bucherer that Rolex now owns. It owns patents for unique takes on components such as the peripheral rotor and a “floating” tourbillon. It is unclear though how Rolex intends to leverage the brands that came with Bucherer AG in the acquisition.

2. Lil Yachty and Shawn Mendes sport summer bling Audemars Piguet and Patek Philippe

Though awards ceremonies are fewer and farther between this month, that hasn’t stopped stars from showing off their cool pieces. Chief among these was Lil Yachty as he took the stage to perform on day four of Lollapalooza Music Festival in Chicago.

But what if you were more aquatically inclined this summer? Enter Canadian star Shawn Mendes’ company. The “Señorita” singer was spotted in Ibiza wearing a Patek Philippe Aquanaut 5168G white gold with a matching pair of khaki swim trunks – perhaps the best possible combination of horology and colour for a wet day in the sun.

3. Rolls-Royce adds high horology to the dashboard

Fast forward to last week when we heard that Vacheron Constantin also threw its name in the ring! Rather than the deep rouge of the former Droptail Roadster, Vacheron Constantin is adding the Armillary Tourbillon from its Les Cabinotiers line of unique watches to the Amethyst Droptail Roadster.

4. GMTs, chic and elegance are all fair game this summer

For those with more conservative travel needs this summer, GMT watches were the flavour du jour, with Grand Seiko, Longines and Bell & Ross each releasing stunning pieces that help track more than one timezone.

Grand Seiko evokes its Shizukuishi studio by releasing two GMT pieces whose dials reflect the blue skies that hover over their workshop. Both pieces feature the 9S movement that turns 25 this year, with the SBGJ275 particularly featuring a rotating GMT bezel with a spectacular dial conjures the majestic Mount Iwate.

Longines added date and chronograph pieces to its Conquest line this year, but we most enjoyed the addition of the Hydroconquest GMT, which adds a GMT hand for the first time to the black-and-gold dive bezel across all colourways.

Last but not least, Bell & Ross gave GMT fans a square option with the BR05 GMT, which comes with an integrated steel bracelet and satin finish.

German maison Glashütte Original, however, has doubled down on designs that exemplify its unique identity, releasing the square Seventies Chronograph Panorama in summer colours and the elegant Senator Chronometer. The former oozes 70s playfulness, while it is almost impossible for the latter to be anything but a precise, timeless dress watch with its panorama date window, power reserve indicator and second-stop mechanism with minute detent ensuring precise timekeeping and hand positioning.

5. Independent excellence – J.N. Shapiro, Ludovic Ballouard and Roger Smith continue to push horology to new heights

From a watchmaking perspective, few watches get more interesting than California-based watchmaker J.N. Shapiro’s latest release, Resurgence. It is an extremely rare instance of a high horology piece where almost every last component was built in the United States.

The American watch industry is an enigmatic one. Its robust 19th century clockmaking industry is now mainly survived by brands more known for affordability such as Timex and Shinola (Bulova and Hamilton are Japanese-owned and Swiss-made, respectively).

In this context, J.N. Shapiro celebrates the best of stateside horology, evident in the guilloché and damaskeening work, the latter of which is a type of engraving heavily associated with 19th century American watchmaking.

The 38mm time-only Resurgence is limited by production capacity to 30 a year and comes in gold, tantalum, zirconium or steel, with the gold model costing around US$85,000.

Other independent watchmakers continued to push boundaries with their announcements this month, too. Ludovic Ballouard made headlines with the new et Fils Upside Down “Series Gaga”, which adds doodling from his son on the signature dial with upturned indices, retailing for almost US$123,000.

Across the channel, British horologist Roger Smith, whose pieces consistently command record prices at auction, is looking to cause a stir by announcing a one-off Series One piece for British Watchmakers’ Day in March next year.
