A mechanical Movado watch looses or gains about a minute a day!  For the price this watch is quite accurate!  You need to wear it all the time.  At night, if you set it at a night stand it could adjust itself a bit.  Over all a mechanical accuracy is about 15 seconds a day +/- and based on how active you are?  So, I give this watch thumbs up.  For the design, this is a knock out.  Very Attractive, and functional with a unique personality.  If you are not diving all the time you may consider replacing the band.  Good buy go for it.  Also, I researched the 7S26 movement; it is basic when it comes to automatic watch mechanisms these days, but it is rugged.
