Interesting...don't Rolex, Seiko, LF, and others use LIGA for the lever and escape wheels?
Rolex's statement about the new chronergy escapement: "High-technology processes are also used, such as LiGA (micromanufacturing by electroforming) to produce the paramagnetic pallet fork and escape wheel of the new Chronergy escapement."
Seiko: "The 9S66 has a number of interesting features, including a skeletonized, LIGA-manufactured (LIGA is a micromechanical manufacturing process) escape wheel and lever."
LF uses LIGA escape wheels for its natural escapement.
Probably others as well. Is this process less-than-ideal for these components?
Thanks of course to JToddH for the great overview of this caliber.
Best,

Hands On: Unico – Inside Hublot’s Calibre HUB 1240
Following the success of the Big Bang, launched in 2005, Hublot set out on its next big challenge, to create an in-house movement following the same design philosophy of their iconic case. The result is the calibre 1240 “Unico,” which demonstrates the bra...
I had no idea that this movement was so technologically advanced
Thank you for explaining 🙏
Thank you for that great article!
Also the description of the LIGA process is very informative. I am glad you stated that the parts shown are not made for the Unico movement. When Ulysse Nardin started to employ the LIGA manufacturing, they soon realized that it was less than optimal for ...

Unfortunately, I have lost my mail correspondence between 2007 and 2011 ...
... so I have to use my leaky memory to compose a reply. I know that Ulysse Nardin created the so-called Dual Ulysse escapement in their 160 years anniversary timepiece by LIGA process in 2006. Back then, Nickel-Phosphor composition of complex shapes was ...
Thanks Marcus, I appreciate the feedback.
Very possible indeed that modern advances have enabled this process to create components suited for fast-moving and sliding components, and this probably accounts for its use today among mainstream brands/watches. Thanks again, Brandon
I echo Marcus Hanke in thanks for this article
I learned more about the process and it showed Hublot truly is at the forefront of technology. All this for a 'standard' workhorse movement. Regards, MTF
Thnaks very much for the details, pics and explenations!
Looking already very much forward to the UNICO 1280 thread! PS: One small thing: The moonphase calibers are not Unicos but Sellitas with modules...
Quick set date feature
I notice the photo of the quick set date feature is not the unico 1240 but the unico 1280?
