Is sapphire glass worth having on a watch like this?

Yes. Sapphire is much harder than the mineral glass used on most fashion watches, so it resists everyday scratches. It can still chip on a hard impact, but it stays clear far longer.

Can I swim with this watch?

No. The 5 ATM rating covers handwashing, rain and splashes, not swimming or showering. Heat and chlorinated water also shorten the life of the leather strap.

Is the strap replaceable?

Yes. It uses a standard buckle strap, so a jeweler can swap it for another leather or metal band. Check the lug width before buying a replacement.

How does it compare with a mineral-glass fashion watch?

It costs more than basic fashion watches, but the sapphire crystal and steel case are the upgrades you get. If you want a watch you won't worry about scratching, it is the better long-term pick.

Does it need winding or a battery?

It runs on a quartz battery, so no winding is needed. Expect a battery change every few years, done cheaply at any jeweler.

It works well as a gift for someone who wants a recognizable designer watch for daily wear. It is less suited to swimmers or anyone who wants a sporty watch.
