Metal Watch Bracelets

  1. Oyster metal bracelets are known for their long, thick, 3-piece link design. The most popular metal bracelet type among watch bands, the Oyster has a wide center bar that makes each link more durable. They’re considered one of the most functional options and are popular among Rolex bracelets, though they might feel a bit stiff at times.[1]
    • Style: Modern, classic, robust
    • Examples: Rolex models, including the Submariner, GMT-Master II, Explorer, and Daytona
    • Lug width is the distance (in millimeters) between 2 lugs on a watch case. A metal bracelet must match the watch’s lug width; a bracelet that is too small can come loose, while one that is too big just won’t fit.
    • The average lug width for men’s watch metal bracelets is 20 mm, though for both men and women, it typically ranges from 18 to 24 mm.
  2. President bracelets have links that are of a similar width to the Oyster style, but with more total links. Each link is also shorter and denser in appearance. They may not be as durable as the Oyster, but they are considered to be more versatile. President bracelet styles work best for smaller or medium-sized watches.[2]
    • Style: Dressy, formal
    • Examples: Rolex Day-Date, Omega Aqua Terra, Hamilton Jazzmaster
    • According to jewelry & watch expert Bill Green, you can adjust a watch band with a metal bracelet if it has a “snap-down deployment buckle by depressing the spring bar and moving it closer to the center (to make it smaller).”[3]
    • While it’s possible to remove links, Green goes on to say that “there are some watch bands where you don't remove links.” To adjust these metal watch bracelets, you’d “open up the slider on the bracelet—it will slide one way or the other. Once it feels comfortable, snap it back down. Think of it as a belt with a slider.”[4]

  3. Jubilee bracelets feature a 5-piece link design with 3 smaller, polished center links between 2 larger, brushed/polished outer (side) links. They have the same number of links as the President bracelet, but the triple-wide construction of Jubilee watches makes the bracelet's center portion appear narrower. It works on both large and small-sized watches, depending on how you want to wear your watch.[5]
    • Style: Elegant, classy
    • Examples: Rolex Datejust, Rolex GMT-Master II, Seiko Sports GMT
  4. Engineer bracelets are more stacked, with a width consisting of 5 links total. The links are often cut in a hexagon-like pattern, giving them a unique, angular appearance. They can feel heavy at times or look bulky if not paired with the right watch. Engineer bracelets were made with dive watches in mind, and they are still the most popular bracelet choice for sporty and dive watches.[6]
    • Style: Sporty, rugged
    • Examples: Seiko diver and sport models, IWC Ingenieur
  5. Mesh bracelets have interwoven metal wires (usually stainless steel) that give them a flexible, chainmail-like design. They’re known for being comfortable, breathable, and easily adjustable. The design also makes mesh bracelets quite durable overall.[7]
    • Style: Casual or formal
    • Examples: Seamaster Ploprof 600m, Breitling Superocean Heritage 46
    • Shark mesh is a more robust style with larger links often used for diving watches.
    • Milanese mesh is more finely woven, which gives it a more delicate style.
  6. Beads of rice bracelets have a 7-row, chainmail-like structure that includes a center row of small interlocking links. These rounded, polished links are said to resemble actual grains of rice and are surrounded by 2 outer rows of larger links. Beads of rice bracelets are known for their flexibility and overall comfort.[8]
    • Style: Classic, vintage, retro
    • Examples: Omega, Longines, TAG Heuer

Leather Watch Straps

  1. Aviator watch bands have metal rivets near the lugs, which prevent the watch from falling off the wrist. Originally associated with pilot watches during World War II, they are known for their thick and durable construction. Aviator watch bands pair particularly well with chronograph watches (which have a built-in stopwatch).[9]
    • Style: Modern, sporty, military
    • Examples: IWC Big Pilot's Watch, Breitling pilot watches
    • Popular materials for leather watch straps include calfskin, suede, shell cordovan, alligator, sharkskin, and goat.
    • Play around with your watch’s look by changing the strap from a classic, dressy style to a more rugged, sporty one.
  2. Nearly identical to aviator watch straps, Bund straps have a protective leather pad situated between the watch case and the wrist. This extra layer was originally intended to protect the wearer’s wrist from extreme temperatures and burns, while absorbing sweat. The additional piece can be a full cuff or a rounded pad, which can feel bulky for some.[10]
    • Style: Rugged, sporty, retro
    • Examples: Pilot watches made by Stowa, IWC, Laco, and Hamilton.
  3. A double-ridge watch strap is a rare style that most closely resembles an aviator-type of strap. The main difference includes 2 raised ridges running parallel along the strap’s length. It’s also thicker and more robust than other similar straps.[11]
    • Style: Sporty, diver, rugged
    • Examples: Timex Expedition Ridge Chronograph, Apple Watch (Heracles Double Ridge Genuine Leather Band)
    • If you have an Apple Watch with a strap, you should be able to change the strap without tools.
  4. Rally watches have 3 or more large perforated holes below the lugs. They’re inspired by auto racing, which is why they’re known for being lightweight and comfortable. The retro look of rally watch straps makes them ideal when paired with a vintage choreograph (racing watch), and they’re breathable enough to be worn during the summertime.[12]
    • Style: Sporty, vintage
    • Examples: Invicta Men's Racing 48mm Chrono, Omega Speedmaster Racing

Nylon Watch Straps

  1. Originally made for astronauts going to space, NASA straps are made from very durable nylon weave with a Velcro fastening system. They’re longer than other watch bands because they were designed to be worn over a spacesuit. NASA straps are extra durable and are resistant to high temperatures.[13]
    • Style: Utilitarian, military
    • Examples: Omega Speedmaster Professional (Moonwatch), Bulova Lunar Pilot, Timex Main Street NASA Artemis
  2. NATO straps originated as 2-piece straps, while most modern versions are “single-pass,” or one-piece. While 2-piece NATO straps have a separate piece of fabric that runs along under the watch case for more security, single-pass NATO straps loop under the watch and are secured with a buckle. Because they’re typically made of nylon material, NATO straps are water and sweat-resistant.[14]
    • Style: Modern, casual, military
    • Examples: IWC Pilot Watch, Tudor Black Bay, Omega Speedmaster
  3. Zulu straps are very similar to NATO straps, but their materials are usually thicker. They’re one-piece, so they easily thread through a watch’s spring bars for added security. Zulu straps also have 3- to 5-ring straps, so they stay in place securely.[15]
    • Style: Rugged, military
    • Examples: Omega Speedmaster, Seiko Sumo, Tudor Heritage Ranger
  4. Perlon watch straps have a braided, woven pattern made from nylon-like material. They look similar to Tropic watch straps, but don’t have perforated holes, which allows the buckle to slide through an opening in the weave easily. Perlon watch straps are known to be lightweight, breathable, and durable.[16]
    • Style: Modern, formal, casual
    • Examples: Rolex Milgauss, Rolex Datejust

Rubber Watch Straps

  1. Waffle watch straps have a diamond-shaped pattern on top that looks like a waffle iron. Underneath, these straps have large textured holes for breathability. They’re known for being waterproof and easy to clean.[17]
    • Style: Sporty, rugged, diver
    • Examples: Seiko dive watches (including King Turtle), Tissot PRX
  2. Tropic watch straps feature a textured “tapestry” design that includes perforations on the strap. Made from rubber, they are hypoallergenic and UV-resistant. Tropic watch straps are also known for their durability and comfort. When it comes to watch type pairing, they’re a favorite choice for dive watches.[18]
    • Style: Sporty, diving
    • Examples: Rolex Submariner, Omega Seamaster, Blancpain Fifty Fathoms

Basic Watch Band Parts

  1. The parts of a metal bracelet are usually made from stainless steel, titanium, or other precious metals. How the links are constructed can differ between bracelet styles, as can the type of clasp and end links used:[19]
    • Watch clasp: Attaches the 2 ends of a watch band to secure it around the wrist.
    • Watch clasp spring bar: A spring-loaded metal pin securing a watch band to the clasp.
    • Clasp spring bar hole: A watch clasp opening that receives the tip of a spring bar.
    • Micro holes: Small perforations that can be used to make adjustments to the band.
    • Tail short-end spring bar: A spring-loaded pin that connects the free end of the watch band to the clasp.
    • The link: One of the interconnected pieces that make up a metal watch bracelet.
    • End link: A piece that directly attaches to the watch case.
    • End link spring bar: A spring-loaded metal pin that connects a watch band to the case.
    • End piece screw: A threaded screw that fastens the links together.
    • Removable link screws: Small, threaded fasteners used to adjust links.
  2. Like metal bracelets, leather or fabric watch straps contain many of the same parts. They include the clasp, clasp spring bar, and micro holes. While leather or fabric straps are less technical, they have some additional parts that help secure the strap or are mainly visual:[20]
    • Strap/band: The piece of material that secures a watch to the wrist.
    • Stitching: The visible stitched pattern appearing along the edges of a watch strap.
    • Keeper: A small loop that holds down the excess strap after it's fastened.
    • Lining: The bottom layer of the watch strap that comes in contact with the wrist.
    • Strap ends: The parts of the watch strap that attach to the watch case.

What’s the difference between a watch band, strap, and bracelet?

PDF download Download Article
  1. These terms are often used interchangeably, but a watch band is the broadest term for any material that secures a watch to someone’s wrist. A watch strap, on the other hand, is a continuous band made of flexible materials like leather, fabric, or rubber, while a watch bracelet is a specific band made of interlocking metal links, like stainless steel or gold.[21]
    • Both watch straps and bracelets are considered specific types of watch bands.
