I don't have the Verona, but I have a couple of the Carrera Twin versions of more or less the same watch:

I like them, I think they are interesting and a bit different and I like the Verona Twin too.

As for how much we know about them, the information is a bit sketchier. Heuer's production records aren't as detailed or complete as for some manufacturers, but when some of the forum members were able to go to TAG-Heuer, they were told that for every chronograph Heuer sold, they sold 19 stopwatches. So watches were only around 5% of the business at that time - which is probably a few years before we are talking about with the Twins, but still puts some perspective on the numbers of watches being produced.

The Verona Twin was in production for a shorter time than the Carrera Twin too. Whereas the Carreras starting appearing in Heuer catalogues in 1979, along with plain Verona quarz watch ("Modernste Quarztechnologie", according to the brochures :) ), we don't see the Verona Twin show itself until 1981:

Two years later, and they are gone again from the brochures - Heuer was in considerable turmoil at this time. So we're talking a production run of only a couple of years, as far as we can determine from Heuer literature. And whereas the Carrera Twins seem to be available across Heuer's distribution network, the Verona equivalent was only for selected markets - it wasn't available in the UK, for example. So the production numbers become even more limited - any attempt at a figure would be a guess, but it's reasonable to say that these are amongst the rarer Heuers.

Rarity doesn't always translate into value, though. At the time, they were relatively expensive - the Carrera Twin, for example, would have cost you the same 395,- DM in 1979 as its counterpart Carrera 110.253 with an automatic movement (the automatic Verona was the same price too, so we can assume the Verona Twin cost as much as an automatic when it was introduced). Now that quartz is not a new phenomenon, though, they haven't been able to retain the same value over time - I was able to pick up the Carrera Twins for between 1/4 and 1/3 what I would expect to pay for an automatic Carrera of the same vintage. Maybe I was lucky to a degree, but the collectors market does largely concentrate on the mechanical watches - though there is definitely groups of people who specialise in the quartz and LCD watches too.

We don't see the Twins very often on the forum, either in Carrera or Verona guise. Of the Veronas, there is Timothy's watch that started this post and also the one in this post :

but I don't recall having read of any others. I take it from your message that you have one? It's always great to see pictures, if you have any available.

Hope that answered some of your questions a little - feel free to ask some more, I have a bit of a soft spot for these Twin watches :)
