Mitch K's original post sparks a fascinating discussion about innovation in horology, contrasting the recent IWC Eternal Calendar with earlier independent watchmaker achievements. He challenges the narrative surrounding major brands' 'new' complications, highlighting how independent creators often pioneer such advancements years, if not decades, prior. This article synthesizes community insights, exploring the nuances of perpetual calendars, brand innovation, and the enduring appeal of independent watchmaking.

De Bethune DB25 Reference DB25
The DB25 represents De Bethune's entry in the 44.5mm manual-wind category, distinguished by its silver dial configuration within the DB25 series. This reference launched in 2006 and continues the brand's approach to contemporary haute horlogerie complications.
The 44.5mm case is crafted from 18k white gold with a fixed bezel and sapphire crystal. Water resistance extends to 30 meters. The manual-winding caliber DB2105 movement provides a substantial 120-hour power reserve. The watch features a leather strap attachment.
This reference appeals to collectors seeking De Bethune's technical approach to timekeeping in a precious metal case. The extended power reserve and manual-wind operation position it for enthusiasts who appreciate hands-on interaction with their timepieces. The 44.5mm sizing places it in contemporary proportions within the independent watchmaking segment.
But I guess that reinforces your point that no one will be around to check!! Personally, I love the look of the Eternal Calendar and it’s smaller than my Deep Sea Sea-Dweller. The problem is that the price is a bit higher than the Rolex! All the best, Jon
The point of this hobby is that you have to love what you’re wearing / collecting. At least IMO. Many brands from conglomerates have lost their soul. This watch is absolutely beautiful. I have never heard of this before. Thank you so much for sharing.
So many of the independents fly under the radar and their contributions to the field of horology is either lost or overwhelmed by the hype that consumes much of the public’s time and journalistic space.
It may be mathematically accurate for 45 M years but to an astronomical point of view it is not as the watch does not take into account that the Moon is slowly but constantly drifting away from the Earth.
...the IWC is not only a secular perpetual calendar but it's an "Eternal" perpetual calendar and as such not only it takes into account the non-leap year centuries but if works (or should work, as no one would be here to verifiy) until the year 4000, for which is not defined in the Gregorian Calendar if it will be a leap year or not.
I still think the Eternal Calendar looks pretty, apart from the hole in the dial. All the best, Jon
