Top pic...both of these are Ladies' models.
Watch on left is a 4912-1 Touch-Command Oval.
Watch on right is a bit ambiguous...could be either a 4406-1 Oval in 14K goldfill, or a 6406-1 in solid 14K gold. Two things stand out to my eye...the gold-looking case ring (which is normally seen only on solid gold models, and the unmarked case back, with no Pulsar name, HR-MIN markings, or serial number (the slight clockwise rotation is also a bit odd). I would give the magnet holder a look...it should carry some marks indicating whether it is stainless, or solid (14K, 0.585) gold. It is distantly possible this is an 18K case, but it should still carry clear hallmarks, if that were true. The only certain way to tell if a case is solid gold, is to open it up and remove the module; SG cases have a very distinctive internal construction that is absolutely diagnostic. BTW, -1 on the model number indicates a leather strap, -2 denotes a metal bracelet.
