Make sure you know what "perpetual calendar" means, and the battery life,
This review is from: Seiko Men's SNQ101 Perpetual Calendar Solid Stainless-Steel Case and Bracelet Black Dial Watch (Watch)
Just to be clear (because at least one of the customer reviews is misleading):
This watch has a 4-year battery life (not a 10-year battery life).
"Perpetual calendar" means that once you set the date (which is not a trivial matter if the date has not already been set for you by the dealer), you will never have to set it ever again, as long as you replace the battery before it dies. The date will automatically adjust for short months (like February and April) and for leap years.
When the battery gets weak, the second hand will move in 2-second intervals instead of the usual 1-second intervals. That is your cue to get the battery changed before the watch dies, so that the perpetual calendar will continue to keep the date properly with the new battery installed.
To see how to operate this watch, look up "caliber 6A32" on the Internet and you will find a pdf manual.
By the way--it's a very nice watch for the price.
