The Frederique Constant Index | family history
The Index is Frederique Constant's COSC line: the FC-710 in-house caliber carries COSC chronometer certification in a 40mm round case at a price point that no other Swiss manufacture house can match for COSC-certified in-house movements. The watch does not make aesthetic statements; it makes accuracy statements.
FC's entry dress collection: in-house FC-303 movement, clean index dial, sapphire crystal. The Index Automatic 40mm is the most accessible in-house automatic from a Geneva manufacture, full stop.
2016 · Launch with the FC-710 manufacture caliber
Frederique Constant introduced the Index as the technical counterpart to its design-forward lines. The FC-710 is an in-house manufacture caliber developed at FC's Geneva workshop, COSC-certified, with a 42-hour power reserve. Launching it in a clean round case with applied Roman or stick indices was a deliberate choice to let the movement credential carry the reference.

2016-present · Index Automatic 40
The Index Automatic 40 is the current standard reference. COSC certification requires accuracy of -4/+6 seconds per day on the wrist; the FC-710 consistently meets this standard. The clean round case and minimal dial give the watch versatility across wearing contexts. Pre-owned examples represent strong value against COSC alternatives from ETA-based brands.
How to read this family
What to consider before buying a Frederique Constant Index.
- Why choose a COSC-certified FC over a non-certified Longines at a similar price? COSC certification means independently validated accuracy, not just manufacturer-claimed accuracy. The L.U.C from Chopard and AP's 5134 have COSC, but at much higher prices. At the Index's price point, COSC certification from a manufacture movement is unusual. If documented accuracy matters to you, the Index has a specific credential that Longines's L619 does not carry.
- Is Frederique Constant a credible manufacture house? FC developed its first in-house caliber in 2004 and has expanded the manufacture lineup since. The movements are Geneva-made, not outsourced. The brand's positioning is accessible-luxury; it is not in the same prestige tier as JLC or AP, but the manufacture credentials are real and the watches are properly made.

Which ref to buy
The Index is FC's entry automatic: a clean round dial, applied indices, date, ETA 2824-2 or FC's own caliber depending on generation. A straightforward Swiss dress automatic at an accessible price.
- 1Open
Index Automatic 40mm -- entry FC automatic, honest but undifferentiated, competes against Tissot and Longines on price.
- The case for it:
- The Index is a competent, inexpensive Swiss automatic. The dial quality is above average for the price and the case finishing is acceptable. For buyers who want Swiss-made automatic at the lowest reasonable price, this delivers.
- Consider instead if:
- At this price, Tissot PRX and Longines Master Collection offer stronger design identity and better secondary market support. The Index has no compelling differentiator.
