How will the new Planet Ocean influence future Seamaster Diver 300m?

While I am not a Plant Ocean person, its latest iteration has me hopeful for a new Seamaster Diver 300M that:

1. is smaller (38-40mm pls)
2. has a nicer bracelet (love the new PO three-link...pls fix the concave lug interface)
3. does not have a Helium Escape Value

I do like the idea of a ceramic bezel, however keeping the no date wave dial on the most current Seamaster would be nice.

I also think the bezel action could be better, and having a more extreme coin-edging for grip would make things more functional.

What else should be hoped for?

How do you feel about bringing back the 2254 sword hands?

1. I agree with @ErichPryde the size is fine by me at least on my 2254, so lets compromize and go for 40mm. How ever the latest Seamaster needs do go on a diet, it is a thick boy!

2. Bring back the Speedy style bracelet from the 2254. The PO bracelet is nice too.

3. No Way! Its iconic Seamaster. We need the He : https://omegaforums.net/threads/big-problem-with-helium-escape.39163/

4. The scalloped bezel is iconic too, but it could be nice if it was easyer to turn when I am cooking frozen pizza. How about a scalloped bezel with a coin edge?

5. (or d maybe) I like the old wave dial and the gloss black dial from the first co axial better than the new lasered wave dial.

6. Hell yeah! bring back the sword hands! And the triangle at 12 and rectangle markers too.

7. Do NOT ditch the lyre lugs in favor of the angular case of the PO. NEVER!

Fun discussion.

I am basing my comments on changes that inevitably happen right after I buy a watch. In my case it was the latest gen no-date Seamaster in black purchased in early 2025. I love this watch, but it is not perfect. If Omega plays their cards right, I may have to get the new one when it comes out.

1. In the modern world, can the Planet Ocean and the Seamaster be the same size?

I think not, and as the PO is now 42mm, something has to give...

2. If you are not willing to admit the Seamaster never had an acceptable bracelet, there isn't much to discuss. The rubber and/or mesh on the current Seamaster is passable, but not classic in any way.

I love everything about the new PO bracelet except its interface with the new lugs.

3. I don't really care one way or the other on the HEV, however if the "more robust" PO doesn't have one, the Seamaster looks like a poseur with one...

4. The current bezel on the Seamaster, while nice looking isn't very functional (especially if your hands are wet). Additionally, my Baltic has better ratching action. Omega can/should do better.

5. Aluminum wave dial and ceramic bezel...can we agree on this one? Case could be thinner too...

6. 2254 sword hands...I am sure we can all agree on this one.

7. After getting the Ed White speedy, I find the Lyre lugs too fashionable; not a deal breaker, but why not be a little different....also there is something weird about the bracelet/lug interface on the new PO...


Just saw the new Speedmasters....I like, especially with a ceramic bezel....Why only reverse Panda?

1. Bring the Seamaster back down to 41mm or maybe 40. Anything less will be too small. Of course thin out the case as part of the smaller size.
2. Keep the 5 link design bracelet but make the watch compatible with the 41mm AT bracelets in case someone wants to change it up. The 2500 caliber Seamasters were compatible with the 8500 movement AT's. I wear my 2220.80 on an AT bracelet.
3. Keep the HEV. It's part of the design language of the Seamaster Pro.
4. Keep the scalloped bezel. Again it's part of the design language.
5. Go back to the thinner waves used on the aluminum versions of the watch. The ceramic waves are too big and thick.
6. I'm fine with either sword or skeleton. I don't really care on this one.
7. Watch needs to have lyre lugs.

I don't mind the PO getting a complete redesign because the first 3 generations of the PO were basically beefier versions of the Seamaster Pro. The redesign gives the PO its own design language. The Seamaster Pro should retain its own language with the waves, HEV, lyre lugs, and scalloped bezel.

Don't need to change much for me. Thinner (upper 12 mm), and smaller (40 mm). Everything else can stay the same. Don't change it as much as the PO changed.

I think we have common ground here. Sorry to touch a nerve.

I think it's a shoe-in now to assume that the new SMP is gonna be under 42mm, since the new PO is 42mm.

I think it would be around 40-41mm with an updated case, bracelet ± taper, but I think (and hope) that they will keep the HEV, since it has been a staple of the Diver 300M since 1993, and the PO is only 20 years old, but you never know.

I also think it'll also start around $8,000 USD, which is quite a shame TBH.

Don't forget the 37.5mm PO. Probably wasn't a big seller since since proportions were terrible. Small watch with a fat case.

Omega is probably glad most ppl don’t know about this one.

1. SMP ceramic size is fine by me, 2254.50 size is even nicer. 40 or 42mm doesn't make a difference to me. I don't even think the 1mm or so difference in thickness matters. The ceramic SMP is heavy, though.

2. I think the Bond bracelet belongs on the SMP. A tapered Bond would be an abomination. If they would slim down the SMP, put an aluminum insert and sword hands on it, then you could offer it on a 1610 bracelet from the 2254.50. The Bond and Peter Blake are different Seamasters.

3. Keep the HeV.

4. Keep the scalloped bezel.

5. The old style wave dial is neat and unique so I wouldn't mind seeing it come back.

6. Yes to the sword hands! Yes to an aluminum insert! Yes to the triangle at 12 o'clock and rectangle indices, too!

7. Ditch the lyre lugs?!? Are you nuts?

Any guesses as to when they might release a new version? I would love to see something soon, but my gut is telling me at least two years.

This is what Grok thinks (all hail the child of Elon) Grok just went straight to this tread for tha answer.

Looking further ahead (2026–2028 speculation):

• Omega might finally refresh the classic Seamaster Diver 300M Professional (the Bond watch) - rumors have swirled for years about a slimmer case, possible 39–40 mm mid-size option, and an upgraded bracelet.
• Continued push toward sustainability, even more advanced Master Chronometer movements, and perhaps more precious metal or ceramic-heavy variants.
• The overall trend seems to be sharper angles + slimmer wearability while keeping the wave dials, helium valves (where appropriate), and that iconic orange pop.

Omega rarely goes full sci-fi with the mainline Seamaster (they save the wildest concepts for limited editions or Ultra Deep experiments), so the "future" likely stays elegant, modern-professional, and very much rooted in dive heritage - just executed with cleaner lines and better proportions.

And Chat GPT

Predicting the exact design of a future Omega Seamaster Diver 300M Professional is speculative, but we can make educated guesses based on trends in watchmaking, Omega’s history, and recent innovations:

---

1. Evolution, Not Revolution:
Omega tends to evolve its designs rather than make drastic changes. Expect the core DNA—distinctive skeleton hands, scalloped bezel, and wave-pattern dial—to remain.

2. Materials Innovation:

• More ceramics and sapphire: Expect further use of scratch-proof ceramic for bezels and dials, perhaps even full ceramic or titanium cases for lighter weight and greater durability.
• Sustainable materials: Omega may introduce more eco-friendly straps or recycled steel, reflecting industry trends.

3. Movement Upgrades:

• Advanced Master Chronometer calibres: Future models may feature even more accurate, antimagnetic movements, possibly with increased power reserve.

4. Enhanced Functionality:

• Smart features: While the Seamaster is a mechanical icon, subtle tech (like METAS-certified anti-magnetism or improved lume) could be introduced, but a full “smartwatch” Seamaster is unlikely.
• Improved water resistance: While 300m is the standard, slight improvements or new helium escape valve designs could appear.

5. Design Tweaks:

• Thinner cases: Advances in movement design may allow a slimmer profile.
• Integrated bracelets: Omega may experiment with more seamless bracelet/case integration.
• Color experiments: Expect new dial and bezel colors, limited editions, and bolder colorways, considering recent green, blue, and white variants.

6. Sustainability and Customization:

• Greater focus on sustainability and personalization, such as more strap options or caseback engravings.

7. Vintage Influences:

• Expect nods to the past, such as heritage dial fonts, vintage lume, or “No Date” editions.

---

What won’t change:

• The Seamaster’s recognizability, dive capability, and professional finish will remain hallmarks.

Example of a possible future Seamaster Diver 300M Professional:

• 42mm titanium case with ceramic bezel, sapphire wave dial, Master Chronometer Co-Axial movement, 5-day power reserve, improved helium escape valve, quick-adjust clasp, and a choice of NATO straps made from recycled ocean plastics.

---

In summary:
A future Seamaster Diver 300M Professional will blend classic Omega elements with new materials, improved mechanics, and possibly eco-friendly initiatives—always honoring its dive watch legacy.

Seems that Ai is more conserned with materials and sustainability than we are.

Boo, ceramic. If they're going back to the traditional wave style, it appears matte. A glossy ceramic insert is all wrong. Suppose matte ceramic would work. I'm just not a fan, but I do love my green SMP.
