School me on Andrew Grima "Emerald" Omega De Villes

In my quest to find another vintage Omega to complement my Seamasters and Geneves, I've run across a few De Ville "Emerald" models designed by famed jewelry designer Andrew Grima. Unfortunately, not much information is available online, nor can I find pdfs of older Omega catalogs that list them. Can the collective knowledge of the forum please school me on these watches? A lot of them are listed as ladies' watches, but are they really? Does a 32mm case size automatically put them in that category? Are Omega's Cals. 620 and 625 reliable/desirable movements? How easy would it be for a watchmaker to service or find parts for it? And lastly, what would be a realistic/reasonable price to pay for one?

Thank you in advance for any information and have a wonderful weekend, OF family!!

so....anyone?
