I've had a few dabbles with Memovoxes but never got any of them to stick...
First off was a watch bought on here years ago for next to nothing - a full set for around £2K - a ca 1997 Reveil with a tan ostrich strap. It had the dial discolouration that seems to affect this model, plus non-hacking movement which I thought was a bit poor for such a relatively modern JLC. Liking things to be mint and not wanting the repair hassle, I flipped it back on SC and it went within 5 minutes. Pic below shows the dial issue (but not my actual watch).
Next I was considering the Master Memovox as a 40th present and it was a toss-up between this and the Chrono...eventually I chose the chrono. I still keep an eye on this Memovox though and if I do move the chrono on I'd replace it with one. Berrys Leeds have a nice used one

After reading a Hodinkee article, then a TZ one with a lovely refurb story that had a vintage Memovox in it, I bought this a couple of years ago from Chronext in their Jan sale:
Coming from larger watches once I opened the box I immediately felt it was too small and didn't suit me, though I realise now I was probably hasty in making my decision. The pic above is somewhat flattering imo: I found this watch to wear smaller than its 37mm, maybe because of the lack of bezel, or better put, the curved bezel, or maybe the dial size relative to case, I can't remember but it just didn't 'bite' like some watches do. Sometimes I regret not giving this piece more time, it was a great example and well priced at £2300. However, I can remember feeling it was a very strong 'no' and in fact also that my tastes were more modern and that vintage was just a bit too dainty for me.
So my advice would be to take your time and try on as many as you can.
