Back in November of last year, Louis Erard teamed up with independent watchmaker Vianney Halter to release the Le Régulateur Louis Erard x Vianney Halter II (though they have been collaborating since 2020). It’s a watch that pairs the regulator display that’s a Louis Erard signature with Halter’s steampunk-y and sci-fi influences. Now, the model is back in a fresh monochrome expression called the Le Regulateur Louis Erard x Vianney II Worldwide alongside a world tour with regional variants.


What do they mean by a world tour? Well, Vianney Halter and Manuel Emch will be setting off to visit a selection of cities across the world to present the watch. In each city they visit, two versions of the watch will be available, the ‘Worldwide’ which is available everywhere in a global limited edition of 178 pieces and a city exclusive edition limited to between 18-25 pieces. Fortunately you don’t have to be too worried about missing out on a particular model because the difference is simply the colour of the seconds with the standard Le Regulateur Louis Erard x Vianney II Worldwide in blue. Just enough of a difference to make them feel distinct from each other without completely reinventing the wheel every time.

So far only four of the special editions have been announced, alongside the dates they will be available and where. The first leg of the trip sees them in east Asia:
23.09.2025 – Takamatsu, Japan, Eye Eye Isuzu, Rhodium seconds hand, 25 pieces
24.09.2025 – Bangkok, Thailand, Anthracite seconds hand, 18 pieces
26.09.2025 – Hong Kong, Purple seconds hand, 25 pieces
30.09.2025 – Singapore, Red-gilded seconds hand, 25 pieces

More cities and dates are due to be announced in due time. Given that they are calling it a world tour, I would predict at least a handful of stops across Europe, the Middle East and perhaps America. Though if you can’t attend any of the events, you can always go for the Worldwide. All of the variants are nice adaptations of the 2024 original with tone on tone monochrome displays in silver-grey, as opposed to the silver and salmon bi-colour of the original. While the dual tone emphasised the steampunk aspect of the design, in its new colour scheme it highlights more of the sci-fi element, further shown via the ‘Live long and prosper’ inscription on the back.

At CHF 4,500 (approx. £4,200) it’s a slight bit pricier than the original but only be a reasonable amount in keeping with inflation. Not to mention the added effort of producing 5 different hands for the special editions and the fact they are more exclusive.
