The Omega Seamaster Professional 300m was first introduced with a ceramic bezel in 2012. This new watch introduced several notable new updates to the Seamaster Diver including the co-axial movement, a ceramic wave pattern dial and new case dimensions. This watch was a marked update and brought the Seamaster into the modern age.
The one feature that many watch enthusiasts believe has not been brought into the modern age, however, is the bracelet. This design does not taper like it would on a Rolex or Speedmaster and the 1990’s link design feels clunky and outdated.
Not to worry though because the Seamaster 300m has a lug width of 20mm and because of its dive watch styling is a versatile strap monster. And I’ve picked out six incredible straps that make the Seamaster 300m look professional and are better than the enormous bracelet that it comes on!
Tom's Strap Choices for Omega Seamaster
Original Highley - Light Brown

I recently filmed a video talking about how no matter how many straps I fall in love with, I always find myself coming back to the Highley. It is the quintessential leather strap design hand made from the highest quality materials.
This is the light brown colour. A more natural shade of tan that I think compliments the vibrant blue dial brilliantly. This strap features the classic 6mm of padding which not only creates its beautiful domed shape but also suits the Seamaster particularly well. I mentioned in the introduction that this model of the Seamaster introduced Omega’s Co-Axial movement. A brilliant innovation in mechanical watchmaking but one that comes at a cost. This Seamaster 300m is 13.5mm thick, a chunky profile for a time and date only dive watch. But the Highley’s padding allows the strap to flow into the case making the overall wearing experience far sleeker
Overton - Light Grey

I love a grey and blue colour scheme. It’s something about the two metallic tones that work so well together. I also think that suede straps look awesome, but I don’t see them often enough out in the wild.
This is the Overton in Light grey. A strap with classic style stitching, slim padding and the softest, most velvety suede layer I’ve felt since my Fiancé bought a super soft suede jacket! While I am a big fan of the combination of modern watches on vintage style straps, in this case, I feel the grey modernises the Overton. Which is actually a better fit for this very modern dive watch.
Radius - Navy Blue

Rubber straps are another dive watch classic combo. And with the addition of a butterfly clasp on this cut to size strap, they’re practical too. Water resistant and flexible these straps are comfortable and durable which makes them perfect for the Seamaster wearer that enjoys more daring weekend activities.
The Navy Blue colour on this strap compliments the blue of the dial nicely and also gives you that OEM look without having to fork out for an OEM strap. I also think the white would look incredible on this watch, setting off the white text on the dial. But you can't beat blue on blue either.
Signature Nylon - Blue & White

This list wouldn’t be complete without a military nylon and of course it has to be blue and white. The Seamaster and military nylon combination is one that is steeped in history as on many occasions a Seamaster has been issued to armed forces. The current Seamster 300m is a bit too flashy to be as utilitarian as those original watches but nonetheless it still looks great on nylon.
The blue and white colourway speak to the modern design of the watch and compliment the text on the dial. The signature line of military nylon straps benefits from supple nylon that makes for an extremely comfortable fit. This is especially useful on the Seamaster, a watch that is already thick before adding two layers of nylon below it. The slight shine to the material also compliments the highly polished finish on the head of the watch aiding its modern aesthetic.
Oblique Mesh

The Seamaster 300m suits a mesh bracelet brilliantly. I’m clearly not the only one that thinks this as Omega themselves have released a swathe of Seamaster editions on this style of bracelet, including the flagship No Time to Die full titanium edition.
The oblique mesh is perfectly suited to this watch as not only does it add a touch of class to the styling but is also capable of accompanying the watch for what it was designed for – diving. The 316L steel construction is fully water resistant and will also hold up well against sea water and the clasp is able to be adjusted on the fly without any tools meaning it can be worn over your wetsuit and then tightened back up again afterwards for a seafood dinner at a beach side restaurant!
TidalPass - Sand Beige

Sticking to the theme of getting your Seamaster wet and pushing it to its limits we have the TidalPass rubber single pass strap. There are loads of great colours available for this strap and I picked Sand Beige as it complements the blue dial well but is its own accent colour. Biege is a great colour choice when you have had enough of seeing black or white straps on watches. It’s different enough to stand out but still retains a classic aesthetic, the same couldn’t be said for something like orange or yellow.
Final Thoughts
The ceramic Omega Seamaster 300m is sure to be a future classic having pushed the Maison’s watchmaking into the modern age and starring in countless films and TV series. It’s a true modern tool watch that also fits the role of luxury and aspirational timepiece. I think I’ve also shown that it can suit a wide range of strap styles. But which one does it suit the best?
I want to hear your thoughts so let me know which strap choice was your favourite for this Omega Seamaster. And while you're at it, what are your opinions on the Helium escape valve design? I can never decide whether I like it or not!
