for example, has Richard Mille become mainstream? Defined as ordinarily available?? Richard would probably shoot me for suggesting such a thing!
Independent: GF 24 Second Incine, white gold, dark dial. Just love the speed of the escapement - mesmerizing.
Mainstream (and apologies to Richard for this): RM002 ti - the sports watch, now iconic, original design.
Not likely to buy or be able to buy either in the near or far future!
