Question about cards included in “Full set”

It's pretty simple, a METAS watch has three cards, Warranty, Pictogram and Chronometer. Otherwise just the Warranty and Pictogram card.

If it's a Limited Edition watch, say Ultraman, the LE info is on the Pictogram card, there is no special LE card.

My Apollo 11 50th anniversary has 3 cards, no LS card, so they must have stopped with the LS card at a certain point.

That has to be a rare exception (there are always exceptions) as it was not Omega policy to include a special card. All the six LEs I've ever had from around 2015 onwards had the LE info printed on the Pictogram card, and there was a separate booklet or trifold insert with info about the edition along with the individual number. But never a separate red card. The Quantum of Solace appears to be an Omega quirk from around 2008. The Apollo 11 35th watch from 2003 didn't have a special red card, so it must have been a short term idea for that QoS watch era.

They basically stopped issuing the Limited Series/Limited Edition card when they stopped issuing the Chronometer Certificate card, which is about 15 years ago, so you're a little late to the change.....
