Takes 11 button presses to reset altitude and it's recommended that you reset before each use for accurate data. It doesn't look as nice as the rs200sd.
Experience:
I ended up splurging and exchanged the rs200sd for the s625x. So far after using it for 11 workouts the 625 does everything I need and more. I upload the data both to the internet service (Polar Running Coach) and the included software (Polar Precision Performance) after each workout. The Precision software allows for tracking of an immense amount of data, to list a few: HR, altitude, speed, distance, avg, speed, splits, time, notes, temp, and weather. Ther are ton's more data options to track that I haven't listed.
I haven't purchased the bike add-ons yet but I wil eventually. I read that the CS100b is a great companion bike computer for $65 and you can use the speed sensor adapter with the watch as well.
Minor Issues:
I've only noticed a couple minor issues so far. The chest strap doesn't seem to work as well as the one that came with the newer rs200sd, this one needs to be wetter. Also, I've had some incorrect HR readings. I'm pretty sure it has to do with elctromagnetic interference like it states in the manual. It happens rarely and I can correct it with the software after the data is downloaded. This may be nit picking but I think the watch is huge and ugly. I can't wait for Polar to come out with a slicker version like the rs200sd.
Verdict:
I'm very happy with my purchase. Although I didn't initally want to spend so much money I really believe it was worth every penny. This device has every function that I've wanted thus far.
s625x worth the $
