Nirva Day Date Automatic 25 Jewels cal. AS2066 Stainless Steel
As far as watches that I have acquired inexpensively, yet still get appreciable wrist time, this fairly unknown item is a favorite. When they say “what are the three most important aspects to a watch….dial, dial, dial”, they are referring to this guy. Even my most reserved multi-Rolex aficionado pals grin when I break this one out. I wouldn’t exactly call it a sunburst, but maybe a term from my gemological studies is apropos---chatoyant. I have owned it for quite a few years, but generally only wore it when I felt a lively green vibe was on call. Then it finally came up in the service rotation, and now that it has been sassed-up I buckle it on a couple of times a month. I think I will always own this one.
In a horologic sense, it isn’t anything to write home about, a generic AS 2066, the ubiquitous 70’s “Crystal” dial, and an interesting case. But the treatment of the dial is what wins me over, and….it’s running rather well for a 50 year-old wristwatch. Anyone know any detailed info on this brand?
