As you can see, I have both. I had a small inheritance (£3.5K) in 2008 & I was looking for a "serious" watch. The candidates were i) a no date Sub & ii) a Speedy.
Because I was young & stupid the Hesalite & the daily manual winding put me off the Speedy, so I went & tried the Sub (remember when you could do that). It felt unbalanced & the bracelet felt flimsy (they used hollow links in those days) & it would have cleaned me out. The Speedy was only £1,600 in 2008.
The search began again & I came across a 2254 - just like the Sub it was W/R to 300m & COSC rated. I thought it felt better (solid links) & looked MUCH better, so I began looking. I got a 1 year old example with box, papers & a year on the Omega warranty in Watchfinder for £895!
Watchfinder was an independent with only 1 shop in those days.
The Speedy urge never left me & I finally got one last year. Never did get the Sub, though I did get a DateJust 41 in stainless steel for my 50th this year - 3 great watches, all individual but all complementing each other in a collection.
