I’m not sure in terms of the reps but I do have a familiarity of this topic in terms of the gens. So afaik, firstly, the gens with Rose logo on the dial is all discontinued and are getting rarer these days because of that, yet weirdly enough, the movement inside of them is the ETA movement.
On the other hand, upon successfully manufacturing their own in-House movement Manufacture Calibre MT5612 with COSC Standards, Tudor commemorated this by changing the logo on the dial from “Rose” to “Shield”. For collectors, the one with Rose logo and smiley dial are highly sought after due to its discontinued status. IMHO quite an interesting story behind a brand that sells affordable gens.
