Some of us don't need much out of a watch to make us happy — understated good looks and a face without much flash are plenty. But there are some of us who need more, who find beauty in the sheer complexity of masterful watchmaking. The Tag Heuer Monaco V4 Tourbillon Watch is made with the latter in mind, as it features the world's first belt-driven tourbillon (the most complicated watch component around), all of which is fully visible through the face and case back. It also features a polished black titanium case, a beveled sapphire crystal, a sapphire case back, water resistance to 50 meters, and a hand-stitched alligator strap. So if you're the kind of guy who likes to keep things complicated, this watch has your name written all over it.
Your phone is thin. Your laptop or tablet is thin. So why not your watch? The Tag Heuer Carrera CH 80 Chronograph Watch fits the bill, boasting a high-tech Calibre CH 80 movement that offers an 80-hour power reserve yet measures only 6.5mm thick. On the outside, you'll find a traditional chronograph face with a minutes counter at 3 o'clock, an hours counter at 9, and a small seconds at 6, a polished steel case with faceted lugs, a racing-inspired perforated calfskin strap with red lining, and, of course, a sapphire crystal case back so you can admire the engineering.
