IWC Portugieser Automatic IW500710 42mm Dark Blue Dial Stainless Steel Watch (7-Day Power Reserve)
TL;DR: The IWC Portugieser Automatic IW500710 is a 42mm stainless steel men’s watch with a dark blue dial, sapphire crystal, and an automatic movement delivering a full 7-day power reserve with a dedicated indicator, plus date and small seconds.
The IWC Portugieser Automatic (Ref. IW500710) is a go-to choice if you want a clean, upscale watch that feels substantial on the wrist but still reads like a classic dress watch. The 42mm stainless steel case and 14.2mm thickness give it real presence, while the Portugieser dial layout keeps everything balanced and easy to read. The dark blue dial is the highlight here, offering a richer, more modern look than silver, and it pairs well with both business and evening wear.
The big advantage of this reference is convenience. A true 7-day power reserve means you can take it off for a few days and it’s still running when you come back. The power reserve indicator makes it easy to know when it needs winding, and the small seconds keeps the dial visually active without turning it into a busy design. You also get a practical date display, and the watch is protected by sapphire crystal for everyday durability.
