Two-tone watches are heavy. That is the deal you make: solid gold on the bezel and through the bracelet adds real mass, and you accept it because the watch looks like it cost something.
The 2297.80.00 does not make you take that deal. The base metal is titanium, not steel — so you get an 18K yellow gold bezel, gold-toned hands and gold links running through the bracelet, on a watch that weighs less than the plain steel version of the same chronograph.
It is the only genuinely light two-tone Omega of its era, and that combination — real warm gold sitting on cold grey metal — is what decides the strap.
The fit: 20mm
The 2297.80.00 is the 41.5mm Seamaster Professional chronograph case, and the lug width is 20mm.
Two collections will fit it:
- Our Seamaster 300 straps name this generation in their compatibility list and run 20mm, 21mm and 22mm — select 20mm. Every pick below comes from here.
- Our Diver 300M straps also cover 20mm if you prefer that cut.
Buckle colour is worth an extra second on this reference. Most Omegas here are steel and silver is the obvious answer. Yours has a solid 18K yellow gold bezel and gold in the bracelet, so Gold is a genuine option rather than a novelty — it picks up the metal that makes the watch what it is. Silver stays closer to the titanium. Both are defensible; look at which half of the watch you want the clasp to belong to.
Spring bars are included, and the Omega strap installation tool is worth using — titanium marks more easily than steel and the lugs show it first.
What you own
A 41.5mm titanium case with an 18K yellow gold unidirectional bezel, around 16.5mm thick, water resistant to 300 metres, with a domed anti-reflective sapphire crystal and a screw-down crown. The dial is the blue wave with luminous gold-toned hands and dot-and-index markers, the date sits at 3, and the bracelet is titanium with gold links. Inside is the calibre 1164, a certified chronometer with somewhere between 42 and 44 hours of reserve depending on which source you trust.
Its siblings are worth knowing so you can tell them apart at a glance: the 2298.80.00 is the same watch in plain titanium with a blue bezel insert, and the 2296.80.00 swaps the yellow gold for pink. All three share this case and this 20mm lug width.
Why the usual gold advice works here — and where it doesn't
There is a rule of thumb that warm brown leather belongs with gold. It is right often enough to be repeated everywhere, and it is wrong on some watches. The distinction is worth understanding, because it is what makes this reference easy.
Modern Omegas with gold accents frequently use Moonshine, a paler alloy. Warm straps fight a pale gold and drag it towards brass.
Yours is not that. This is straightforward 18K yellow gold — a solid bezel, not a coating or a pale alloy — and it is sitting on titanium, which is darker and greyer than steel. That combination does two useful things. The gold reads unambiguously warm, so warm straps agree with it rather than competing. And the cold grey case behind it makes the gold look warmer still, which means you have more room than usual before a warm strap tips into too much.
So on this watch, the old rule holds. Warm is right. The only question is how warm.
1. Brown — the pairing this watch was built for
Start here. Brown against yellow gold is the oldest combination in watches, and on a titanium case it is better than it is on steel: the strap and the gold agree, the case disagrees with both, and you end up with three distinct tones instead of two competing ones.
It also does something for the blue dial. With brown below and gold around it, the blue stops being the watch's colour and becomes its centre — which is exactly the hierarchy a two-tone diver wants. Brown rubber strap →
2. Bordeaux — richer, and better after dark
The deeper version of the same idea. Burgundy and gold is a dress-watch pairing that almost nobody tries on a diver, and it works here for a specific reason: the blue dial keeps it from looking stuffy, and the titanium keeps it from looking soft.
If brown is the weekday answer, this is the one for a jacket. Bordeaux rubber strap →
3. Black — make the gold the only bright thing
The restrained way to own a two-tone watch, and a legitimate position rather than a cop-out. Black rubber removes every other tone from the wrist, so the gold bezel becomes the single bright element on the watch and the titanium recedes into the strap.
This is the version people describe as tasteful. It is also the collection's best seller, so it is the one that gets worn. Black rubber strap →
4. Beige — the light warm one
Same family as brown, turned up in brightness rather than down. Beige next to yellow gold is softer and more summery, and against a dark titanium case it gives you the most contrast of anything on this list.
Best in warm weather, and the pick that makes a twenty-five-year-old two-tone chronograph look relaxed rather than formal. Beige rubber strap →
Prefer to answer the dial rather than the gold? Blue is the obvious tonal choice — that is the natural route if you own the plain titanium 2298.80.00 instead, where there is no gold to consider.
