Why did Omega change the design of the Speedmaster Professional?

So when Omega made the first Speedmaster Professional 105012, it looked great.

What I'm confused about is why they changed it when they released the 145022, I.e. the first with the caliber 861 movement.

Specifically, why get rid of the tear drop seconds chrono hand? Why get rid of the long hour markers? Why get rid of the step dial?

Those things all made the Speedy look so good, so why change it?

Cheers

Maybe they weren’t hugged enough as children?

If it were up to Omega, NASA would have switched to the Mark II 145.014 Speedmaster.

It may seem obvious to you which features should have been retained but it wouldn’t have been 50-60 years ago and in any event fashions change.

Your timing is slightly off and it wasn’t an overnight thing. The teardrop hand was err dropped around 1967 when the 145.012 was rolled out, the long indices lasted up until 1969 and were carried over to the first of the 861 models, namely the 145.022-68. The step dial lasted longer still, right up until ~1974.

This suggests the changes were evolutionary and done to keep the look fresh, or so would be my guess. Don’t forget the pushers, crown, lume material, font and logo have also changed over the years. Very few products stay truly static.

No knowledge on why things changed, but the ALMOST made everything right again with the new 3861 Speedy. If only they had gone back to the long markers. Then, it would have been perfect.

Second this. I hope they release a version with the long hour markers, then I can get them to fit the new dial to my watch.

Anyone know if there was any design or production reason for the short markers in the first place?

Clearly cost savings. They were running out of Tritium…

I think there is a obvious one: the long tritium markers were masking the smaller tick marks, the short markers let you read the complete track...

Ah indeed! And how come it took until the 3861 to change the number of ticks between minute markers to more accurately reflect the beat rate of the movement? In other words, why was it 4 vs 2 to begin with?

But why switch from a tear drop chrono seconds hand to a flat one?

Do you think it would have been better to retain the exact look of the moonwatch in the hesalite version and put the new look on the sapphire?

That way people could get a 105012 looking watch, just with an updated movement, and everyone else could get the new look in the sapphire.

Because the original 321 movement had a slower rate than the later 861/1861 and 4 marks originally allowed accurate measurement to 1/5 of a second. When Omega changed to a 3Hz (6 tick) beat rate with the 861 they lost that precision by keeping the design the same. The 2 marks on the 3861 dial allows accurate 1/3s precision. The broad arrow watches have 3 marks which allows 1/4s precision due to the higher still beat rate at 4Hz from their rather more sophisticated 3303/3313 movement.

They actually changed to a 2 mark design long before the 3861 came about, the FOIS has it and that’s from 2012. They also used it on several LEs, the Snoopy 2 and Ultraman to name but 2.

I see, so while the 321 beats at 2.5Hz / 5 ticks, presumably because they couldn't actually squeeze in a 6th tick mark on the dial for the 3Hz / 6 ticks of the 861/3861, at least 3 ticks more accurately aligns with the faster beat rate, even though it's actually a reduction in precision?

They would also have to put an applied logo on the hesalite to make it look like a 105.012. And a simpler caseback with no “flight qualified” text.

Would it have been better to do all this (at least on one version). Yes.

Would Omega do it on a standard Moonwatch. No.

But maybe on a limited edition with a premium price…. 😉

They are a business focused on revenue & profit growth. Always keeping the same design you can run the risk as a manufacturer of being viewed as stale, not forward thinking, behind the competition, behind the times, etc.

One function of design evolution is a carrot on a stick and a rationale for customers to keep coming back to the trough. I realize there are some exceptions to this, but they are rare outliers. Follow the money. Without healthy revenue & profit everything else is just aggravating noise and expense dragging profit down.

Imagine pleading the importance of static design ethos & consistency to the board in a meeting with a huge chart behind them with a red arrow going aggressively down and to the right. I don’t think that speech would win the day. Follow the money.

There are reasons for all the changes but most are supposition. Lot's of good explanations. Maybe Omega management can chime in?
