The market may not be there, but Omega has been known to simply experiment with 'creating' a market. Consider the many re-issues they've done in the past few years...how many of them were actually 'asked' for prior to release? The only one I can think of was the 321 in stainless steel, but due to the cost, it's out of reach for many first-time collectors.
In the normal range, we have things like the Seamaster 300 with the lollypop hand in black and blue (I think based on the original 14755). A beautiful watch, but was anyone asking for one? The lovely sector dial Omega CK 859, which only suffers in design due to the hour and minute hand being too close in size....was anyone asking for one before it came out? I could continue, but you get my drift.
Omega could easily come out with the 165.024 with big triangle, but these things need to happen 'at the right time'. Right now, they have the new Ultra Deep and the Bond Seamaster 60th Anniversary...it would be stupid to release another diver that is 'special'. I'm sure Omega knows which models sell the best per region....where I am, my AD says that the normal Seamaster Pros fly off the shelves, especially if they have the black or white versions. The Seamaster 300s are never in the AD for a long time at all, but I have yet to see an Ultra Deep.
I think Omega could release it in, say, 3 years from now to coincide with the anniversary of the introduction of the big triangle (1966 or 1967 approx.?). So, wait until 2026 and see what happens. That's what I'd do if I was Omega, anyway. I'd price it around 9-12k USD, and it would have the best movement available, along with the usual modern Omega stuff (see-through caseback, independent adjustable hour, differing lume colours on the handset and bezel, etc.). I'd make it no-date, of course, and with a ceramic bezel that is fully lumed like what you see with the Blancpain Fifty Fathoms.
What say you?
