Both pair the openworked dial with an FC-310 automatic movement, a 41 mm case and a bracelet plus a matching rubber strap. The launch specifications and prices are documented; current stock and pricing are not established.
What the Highlife Automatic Skeleton shows
The skeleton treatment opens the dial to reveal parts of the movement, while a display back offers a second view from the case side. WatchAdvisor’s December 10, 2021 presentation describes an Earth motif cut into the dial, with the balance visible at 12 o’clock and the barrel around 5–6 o’clock. That is the presentation’s description of the design, rather than an independent measurement of the mechanism. WatchAdvisor

The two references were specified with hours, minutes and seconds. Their reported dimensions and construction are a 41 mm case, 10.84 mm height, convex sapphire crystal, display back and water resistance up to 5 ATM. These are the 2021 launch specifications, not a current product-page check. WatchAdvisor
FC-310 movement: specifications and what they mean
The FC-310 is an automatic movement reported with 26 jewels, a frequency of 28,800 A/h (4 Hz) and a 38-hour power reserve. WatchAdvisor’s launch presentation and Fratello’s September 27, 2021 coverage report the 38-hour reserve and 28,800-vph rate. WatchAdvisor Fratello Watches

Those figures describe the caliber’s stated specifications; they do not establish how long a particular watch will run in daily use. WatchTested has described the FC-310 as based on the Sellita SW200-1, but that identification is secondary reporting and is not confirmed by the official or contemporaneous sources cited here.

The two 2021 references compared
| Reference | Case and bracelet finish | Dial/ring presentation | Additional rubber strap | 2021 launch price including VAT | Limited quantity |
|---|---|---|---|---|---|
| FC-310DGSKT4TNH6B | Stainless steel with titanium PVD coating; three-link coated bracelet | Dark grey | Dark grey | €2,395 | 888 pieces |
| FC-310NSKT4NH6B | Brushed and polished stainless steel; three-link steel bracelet | Navy | Navy | €2,295 | 888 pieces |
WatchAdvisor’s December 10, 2021 presentation lists both references with the same core movement and case specifications. The €100 difference is between the stated launch prices only; it should not be read as a current price comparison. WatchAdvisor
Bracelet, rubber strap and interchangeability
Each edition was presented with a three-link bracelet and an additional color-matched rubber strap. Frederique Constant’s 2021 brochure describes the broader Highlife collection’s push-pin interchange system: two push-pins at the bracelet end release it from the case. The brochure also describes the collection’s globe dial decoration. Frederique Constant 2021 brochure
That collection-level system does not prove that every third-party strap will fit these particular skeleton references. For a replacement strap, confirm fit for the exact reference rather than relying on the broader Highlife description.

What the launch prices and limited edition mean for buyers
The listed prices—€2,395 for FC-310DGSKT4TNH6B and €2,295 for FC-310NSKT4NH6B—included VAT and were reported as 2021 launch prices. They are historical figures, not quotes for today’s retail or second-hand market. The 888-piece limit applies to each reference as presented at launch; it does not establish how many remain unsold or available.
Current availability, authorized-retailer pricing and secondary-market values for either reference have not been established here. Frederique Constant’s official product pages found for collection context describe current Highlife COSC models, not these 2021 skeleton editions, so they do not confirm that either skeleton reference is still offered. Frederique Constant
If considering a listing, match its reference number to the edition you want, then verify the seller, condition, included bracelet and rubber strap, and warranty or service documentation. A limited-edition count alone is not proof of authenticity or present-day scarcity.
