COSC's New Excellence Chronometer Standard Explained + A. Lange & Söhne Chicago Boutique Tour (2026)

The world of horology just got a whole lot more exciting! COSC, the renowned Swiss Official Chronometer Testing Institute, has unveiled a new, stricter standard for chronometry, and it's causing a stir in the watch industry.

COSC's 'Excellence Chronometer' Standard:
COSC has raised the bar with its new 'Excellence Chronometer' certification, pushing the boundaries of precision timekeeping. While their current chronometers are known for a daily rate tolerance of +/- 10 seconds, the new standard demands an even tighter tolerance of +/- 6 seconds. But here's where it gets controversial—COSC is also introducing more stringent criteria, including increased magnetic resistance and independently verified power reserve durations. This move could spark debates among watch enthusiasts and professionals alike. Will this new standard become the new norm, or will it be seen as an unnecessary complication? Only time will tell.

A. Lange & Söhne's Chicago Boutique:
In other news, A. Lange & Söhne, the esteemed German watchmaker, has expanded its retail presence in the United States with a new boutique in Chicago. Located in the iconic Tribune Tower, this marks the brand's 9th retail location in the US. Charles Langlois, Brand President for the Americas, expressed his enthusiasm, stating, 'Chicago is a world-class destination for watch enthusiasts, and we're excited to showcase our commitment to precision and tradition.'

Hublot's K-Pop Ambassador:
Hublot, known for its bold partnerships, has made a surprising yet strategic move by appointing K-Pop superstar Jung Kook, a member of the global phenomenon BTS, as its global brand ambassador. This decision is sure to turn heads and spark discussions. With K-Pop's massive worldwide appeal, Hublot is tapping into a new audience and cultural phenomenon. But is this a genuine appreciation of the music genre, or a clever marketing ploy? You decide.
