Explore rumors about a new, slimmer 42mm Omega Planet Ocean. Collectors debate design, thickness, and Omega's product strategy. Will Omega deliver a thinner PO?

Aquaracer1's post delves into persistent community rumors about a new, slimmer 42mm Omega Planet Ocean. This discussion highlights the collective desire among enthusiasts for Omega to address case thickness, a long-standing point of contention for many collectors. Aquaracer1's initial query sparks a conversation about Omega's design philosophy and the potential for a more refined Planet Ocean.

Several folks in the watch enthusiast community have rumored that Omega is working on releasing a new 42 mm Planet Ocean with a thinner case. Expected to be released sometime in the final Quarter of this year. I have no sources, no info, other those that have stated employees at Omega AD’s or Boutiques have confirmed this. I personally would be very excited for a new, slimmer PO, but as I always say, “I’ll believe it when I see it!” Anyone heard anything about this? Will we get a new, slimmer PO this year?? *Image borrowed from www 🍻

Key Points from the Discussion

A slimmer Planet Ocean would represent a significant design improvement for Omega, especially when compared to the sleeker profile of older 2500-caliber models.
A Planet Ocean with no date and a solid caseback, coupled with a slimmer profile, could better define its role as a tool watch within Omega's diver lineup, differentiating it from the Seamaster Pro line.
Despite hopes for a significantly thinner case, some collectors anticipate the new model might still exceed 14mm in thickness, falling short of the desired 12mm profile.
The original Planet Ocean with the Caliber 2500 movement is often cited as the benchmark for a slimmer and more wearable PO design.
There's a humorous skepticism regarding Omega's product strategy, with some collectors noting the brand's tendency to release numerous variations of existing models.

A Planet Ocean with no date and solid caseback would, I think, signal some extra clarity in Omega's diver lineup, where the Seamaster Pro line is the "everyday watch that's a diver" and the Planet Ocean is the more toolish variety. If they did that while at the same time slimming the PO down a bit they might just have a new Omega diver I'd want to buy!

All improvements in my eyes Ian! But in these hypothetical mock ups, has it now gained a crown guard?

As I’m sure most of us can agree, would be a huge step forward for Omega. If you remember the 2500 cases from back in the day, they still managed a sleek profile, even with the co-axial escapement. The trend for them, even with a relatively thin movement, is to blow the modern cases up like a balloon and see if it sticks 🤷🏻‍♂️ This has been extremely well documented among Omega enthusiasts and collectors alike. We’ll see! And yes, totally agree, no date would also be a bonus ! 👍🏻

Watches like the IWC Ocean 2000 demonstrate that one can do it with a very slender case 👍🏻
