Q: What kind of bracelet does it have, and is it comfortable?
A: This reference comes on IWC's stainless-steel Milanaise mesh bracelet. IWC describes it as moulding snugly to the wrist, and many enthusiasts like mesh bracelets for their fluid, close fit, although some still prefer leather for a more traditional dress-watch look.

Q: Is this watch automatic or battery-powered?
A: It is an automatic mechanical watch, so it runs via its self-winding movement rather than a battery. If it has been left unworn, it can usually be started again with a gentle wind and regular wear. ([iwc.com](https://www.iwc.com/us-en/watches/portofino/iw356506-portofino-automatic))

Q: Can I swim or shower with this watch?
A: This reference is commonly listed at 30 metres / 3 bar of water resistance. That makes it better suited to light splashes and everyday caution than to swimming, showering, or diving. ([jomashop.com](https://www.jomashop.com/iwc-watch-iw356506.html))

Q: Why do buyers often choose the Portofino line?
A: Many buyers are drawn to the Portofino for its clean, minimalist dial and refined, office-friendly look.
