the SSC015 Solar Chrono DOES NOT FIT THE SNE439 Solar Diver. I've been looking for an OEM bracelet for the SNE for a few weeks, with no luck, and decided to buy the Super Oyster w/Submariner clasp and see for myself. There have been a few discussions on the net about the fit, and I can confirm another statement that it does NOT fit perfectly. It's close...VERY close. It will even lock in if you use 1.8mm spring bars, but the solid end pieces are maybe 1mm too long, making the curve of the end pieces NOT match the curve of the lugs. Until I find an OEM bracelet for one of the SNE Solar Diver series (like the SNE435), I'll keep looking.
