The SNK809 (which is black, but there are other colors). This has a 21 jewel movement (generally the 7S26B, but the earlier models have the 7S26). It has a 36mm case (excluding the crown) and18mm wide band.

The other model is the lager SNZG15 (which is black, but there are other colors). This has a 23 jewel movement (generally the 7S36B, but earlier models have the 7S36). It has a 40mm case (excluding crown) and an 22mm band.

Both of these watches are gray market. You won’t see them for sale in US stores.

I’ve owned my SNK809 for several months and love it. Its very accurate for the price. Mine gains about 5 sec/day. You’ll have to spend a lot of money to do better than that in the mechanical watch world.

Two of my friends own the SNZG15, and they seem to gain about 10 sec/day. Note: The fact the SNZG15 has 23 jewels doesn’t mean its more accurate than a 21 jewel movement. It’s larger, pushes more mass (bigger hands), and thus I speculate is inherently less accurate than the smaller SNK809.

I got my SNK809 on eBay for $45 + $25 shipping (2009). However, it was shipped from Hong Kong. It had to clear customs, shipping takes about three weeks, and has more inherent risk. I’d expect to pay more on Amazon if it was shipped from within the US. Similarly, I’ve seen the SNG15 for as little as $105 with free shipping, shipped from Singapore.
