The Tissot Luxury is perfect for guys who like a minimal amount of contrast. With the exception of the minute markers and Tissot branding, the entire watch is done in a classy stainless steel silver. With automatic movement and an 80-hour power reserve, the watch is also very functional.

Built to withstand a beating, Casio's G-Shock line includes some of the most durable watches you can buy. The GG1000-1A5 makes the list in an extremely stylish black and olive colorway. What makes this watch stand out is its analog and digital display. You'll find functions like month, day, date, world time, alarm, and stopwatch, and countdown timer, all on its face. It's also water resistant up to 660 feet, which is a nice touch.

Aptly named the T-Sport Seastar, this watch features a sporty nautical-inspired design. The stainless steel case is contrasted by a black uni-directional bezel, rubber strap, and dial. A combination of white and blue accents are used on the display. A skeleton rear case shows of its automatic movement.

The Diesel Timeframe watch is one of the most interesting options on the list. It features a black ion-plated stainless steel case, a black leather strap, and an iridescent dial, which has a luminescent glowing display. Priced at under $90, it's an extremely affordable way to add variety to any watch collection.

Priced at nearly 50% off, the Citizen Promaster Diver is a great watch if you're sticking to a $200 budget. In a contemporary diver watch style, it features a silver bracelet and case with a blue bezel and dial.

The Citizen Eco Drive World Chronograph A-T proves that intricate watches can be just as popular as trendy ones with a minimalist design. The watch uses Citizen's Atomic Timekeeping Eco-Drive movement, and displays a lot of information including the day, date, world time, and chronograph functions. The watch itself features a gold case, brown leather strap, and grey dial.

The Movado Museum is a minimalist's dream watch. It features an elegant black and gold color combination. The only markings to be found are the signature Movado dot at 12 o'clock and a bit of texture on the premium leather strap.

At just over $70, the Armani Exchange Active Chronograph makes for a very affordable gift. Its simple black and silver design can be appreciated by any guy. With three chronograph sub-dials and a date display, the watch is as functional as it is attractive.

Coming in at less than $90, the Fossil Machine Chronograph is another extremely giftable watch. It features a black ion-plated stainless steel case, a dark brown leather strap, and a black dial with tan accents. The display includes the date and sub-dials for 60-second, 30-minute, 24-hour intervals. In addition to be a very handsome watch, it comes bundled with a matching leather bracelet — another thoughtful touch for gifting.
