IWC built a perpetual calendar designed to outlast all of us 🤯

The IWC Portugieser Eternal Calendar is the brand’s first secular perpetual calendar, mechanically programmed to account for the Gregorian calendar’s century-year exceptions through at least 3999. And the moon phase? IWC analyzed more than 22 trillion gear combinations to create a Double Moon display accurate to one day in 45,361,055 years.

Powered by the automatic caliber 52640 with a seven-day power reserve and housed in a 44.4mm platinum case, it’s one of the most technically ambitious watches IWC has ever made. In 2024, it took home the GPHG Aiguille d’Or, watchmaking’s top overall prize.

IWC took the perpetual calendar it’s been refining for decades and made it basically eternal. Is this the most impressive perpetual calendar on the market today? 👇🏼

PLEASE SHARE THIS:

9 years ago I lost my sister to cancer. It is a pain that never fully leaves you, and seeing young kids and their families face that exact same battle breaks my heart.
That is why supporting the Tyler Robinson Foundation @trfdotorg was a no brainer for me.

Since I cannot attend this year’s Rise Up Gala in Las Vegas on Friday, October 16th, I am donating a $165,000 Breguet Classique Tourbillon to be auctioned off at the event. 100% of the proceeds go toward helping families with the non medical costs of pediatric cancer, giving them what matters most: time together.
Whether you are in a position to bid on the Breguet, buy gala tickets, or simply drop a $5 donation, please consider supporting this cause. It means the world.

🔗 LINKS ARE IN MY BIO to donate directly or reserve your spot for the Gala. Thank you, guys. 🙏

This is not just watch theft. It is the theft of watchmaking history.

The Ulysse Nardin museum in Switzerland was robbed. Having visited the museum and handled these exact pieces in person, this news hits hard.
I am calling on the entire watch community, dealers and collectors alike, to stand together. Please post, repost, and share this video until these irreplaceable pieces are recovered and returned to the museum where they belong 🙏🏻

Only 150 of these exist, and the story behind it is actually worthy of the “Everest” name. 🏔️

The Vacheron Constantin Overseas Chronograph “Everest” ref. 5510V/000T-B923 was released in 2021, inspired by the prototype Vacheron built for photographer and explorer Cory Richards, who wore it during his 2019 Mount Everest expedition.

The 42.5mm case is primarily titanium with a stainless steel bezel ring, paired with a grained grey-blue dial and orange chronograph accents. Inside is the in-house Caliber 5200/2, a column-wheel chronograph with a 52-hour power reserve and the Hallmark of Geneva.

And Vacheron didn’t waste the caseback. The 22K pink gold rotor is engraved with Mount Everest, based on a photograph taken by Richards himself.

150 pieces worldwide. This is easily one of the more interesting modern Overseas references 👌🏼

Alexander Zverev might have one of the most interesting watch résumés in professional tennis 🎾⌚️

Zverev lifted the US Open trophy wearing the Jacob & Co. The World Is Yours Dual Time Zone Tourbillon, a 43mm rose gold watch featuring two independently adjustable time zones and a central 30-second tourbillon.

But the watch gets even more interesting when you look at who’s wearing it.

Before becoming a Jacob & Co. ambassador in 2025, Zverev spent years with Richard Mille, competing in everything from the RM 27-01 Rafael Nadal Tourbillon to the ultra-light RM 67-02 developed with him in mind.

And yes, he actually plays in them.

From Richard Mille to Jacob & Co., Zverev’s watch history is almost as interesting as what he’s been doing on the court.
