How case size wears

As a rough guide, a case of about 23.5% of your wrist circumference suits most people, and lug-to-lug matters more than diameter on smaller wrists. Each reference page has a wrist-fit estimate, and Watch Finder filters by wrist size.

Which strap type?

Rubber or silicone: the practical choice for swimming and hot weather. It doesn't absorb water and rinses clean.
Fabric single-pass or two-piece nylon: light and cheap. A single-pass strap runs under the case, which adds a little height on the wrist.
Leather: dressier, but water and sweat shorten its life. Keep it off dive watches you actually swim with.
Steel bracelet: the most durable, but aftermarket bracelets need end links shaped for the specific case, which brands rarely publish. Buy one listed for your exact reference.

Spring bars and changing straps

The length of the spring bar has to match the lug width. Omega product pages we checked don't publish spring-bar diameter, so measure your existing bars or check the hole size listed for any aftermarket strap. Some bracelets use fitted end links shaped to one case; if yours does, an aftermarket strap may leave a gap at the lugs. If a bar is seized or the case has no visible lug gap, a watchmaker can swap the strap safely. Step-by-step instructions are in our spring bars and tools guide; the method is the same for any brand.

Questions

What is the most common Omega lug width?

Your strap width must equal your watch's lug width. Find your reference in the table on this page; widths run from 13 to 24 mm.

Where do these numbers come from?

From Omega's own product pages. Each reference page links its source and the date we checked it.
