French quartz movement keeps near perfect time. Movement is a 'hacking' type, which means the second hand is frozen when the stem is pulled out, allowing time to be set to the second. Stainless steel case. Water resistant to 150 feet. Not worn much—I have many others. One owner since 1988 when I bought it new. Almost perfect condition (one small scratch on mineral crystal and one scrape on side of case). A very good looking watch with as close as you can get to timeless appearance. Case diameter 35 mm. Battery is a common size and easily replaced. I replaced the battery about a month ago and will supply an extra 4 fresh batteries with watch, so you should be good to 2034! Merry Christmas to someone. email is best, or phone if urgent, but between 10 AM and 9 PM.
