In 2005 I bought 10 or 12 vintage style Eta powered watches from Paul/Abay and put them away after discovering they had the crystal glued to the case and the rotating bezel crammed down over it. The spring wire in the bezel snapped in between the short skirt crystal and bezel neck so it would rotate. This was not good as the crystal and rotating bezel soon fell on the floor.
Looking back, it was really not so bad as I only paid $99 for some of them and $159 for the others. They also had good date overlays, pretty good cases that would accept genspec crystal/case tube, and all models with He valves had working valves. The dials are fair with the comex 5514 dials being a little better and the hands are good with a slight curve in the middle but the no-glo lume filler is too yellow on some...but no worse than genuine 'sunny bunny' watches.
Something else...now new Eta 2836-2 are going for close to $200.
I also bought a few of Paul's 'Ultimate!' submariners and all but one had new genuine Eta 2836-2. The last one had a Seagull clone so I stopped buying them. They were $219 at first but I caught most of them later in a 'Crazy Sale!' for $159.
Fast forward 7 years and now I am giving the vintage watches a second look after giving up on DW cases with their goofy spring wire bezels, non spec case necks etc.
Every one of the Paul/Abay vintage watches came with brand new Eta 2836-2 movements. No used, refurb, or asianclone junk like you see today. They still run fine but need c/o now after being stored so long and that only costs me a few hours and a few bucks each to get them back in gro.
I made a beater out of one of the comex no date 5514 and it turned out pretty good. I used a Clark bezel kit, GS domed crystal, replica tube/crown, drilled the lug holes, and stuck a freshly c/o 17 jewel eta 2846 out of a $25 Jaques Prevard (aka Jack the Perve) watch in it.
I also pressed some solid rods through the lugs like a 5517 using 1.4mm steel rod after boring the case to accept the rods.
These watches are no longer nearly worthless with Etclones everywhere and $200 swissetas.
I still have some 'nos' (Ha!) Abay 1655, oversize Seagull ST19 Daytonas, WLD n/d exp, AK, n/d submariners, 'River' SD, ex II, GMT etc (the WLD AK use the same 36mm case/20mm bracelet as the n/d exp).
'nos' replicas...that's a new concept.
If you keep junk long enough...it becomes 'collectible'.
