Good Watch - Hard To Adjust Band
The good: Good quality. Keeps accurate time. The not so good: The not so good is not a problem with the watch but a problem with adjusting the metal band. And that is not the band's fault. That's my fault. To adjust the band so it fits the wrist one must take out links in the band. A tool comes with the watch to aid link removal. I just could not do it. So I replaced this band with another metal band that has a quick adjust magnetic closure.

Classy fully automatic watch - lots of bling too
Watches with a mechanical movement are becoming more mainstream despite the impact of smart watches and quartz movement timepieces. With a pure mechanical watch, there are no concerns about battery charge so when you pick it up from the nightstand, all you would have to do is give the stem a twist to wind the main spring, reset the time and off you go - and that's only if it has stopped. If it hasn't stopped (it won't if you wear it every day or have a watch winder) you strap it on and you are all set.
I gave this watch my regular accuracy test set against a clock linked to the atomic time source. To my great surprise, it was as accurate as one of my much more expensive mechanical watches (how much more expensive? This watch costs about the same as the sales tax on the most pricy watch in the closet !!)
I use the included watch bracelet tool to remove a link from the watch to get a proper fit. Including the tool in the box saves you the $10 plus fee a jeweler might charge you to make the adjustment - very cool. And you probably will need to remove at least one link - some may need to remove two - since the bracelet has a generous size. Speaking of the bracelet, it's beautiful. I wore the watch today to church and a friend said it had "heavy duty bling" ... But she did say she thought it was beautiful and I concur. Finally, The way the bracelet clasp works is reminiscent of a Longines bracelet i have and that spells quality to me.
The dial is black with chrome shiny minute markers so visibility in good light is excellent. I do not detect any glow in the dark markings on the hands or the minute markers - factor that in for your purchase decision.
I see this watch as serving as your "good" watch for business wear, to don for a meal at a fancy restaurant or for that big date night. I think it has a classic look that (despite the bling of the bracelet) is conservative enough for anyone and any business situation.The only place I wouldn't wear it is to the beach or the gym despite the fact that it has claimed that it is waterproof to depths you probably will never experience.
Accurate, beautiful, real quality that translates to good value and capable of being almost anyone's "good" watch.
