I believe that it would be an 1171-1 bracelet with 633 end links, but could one (or more) of our resident Speedmaster experts confirm wihether or not I'm correct? Thanks!

There are definitely some 71s that came with a 1039, but it whether this was a dealer switch or not isn't clear.

Any of these would be period correct 1171, 1175, 1039, 1116, and Holzer. I think the Holzer could be only period-correct if delivered to Mexico. Occasionally the extract does say what bracelet it was sold with.

I would think 1039/516 , 1116/575, 1171/633 , 1175/640 - all with 71 date stamp.

This may be sacrilege, but I really like wearing the 1175 best.

Agree 👍
It (1175) looks good, a bit less rattle, feels secure, and is comfortable. My favorite for 70's bracelets.

Thanks to all for the replies. Is the 1171/1 a service bracelet? If so, does that significantly devalue the watch if it's otherwise fully original? The watch in question is a 1971 Speedy Pro 145-022. The bracelet has the square logo, not the trapezoid, on the clasp.

Just as a personal preference, 1039 and 1116 are more age-correct. The 1171 was produced then and has been produced more recently. If you can get hold of one from the old production, that would be correct too. IMHO unlike a more recent 1171.

See previos discussion:

https://omegaforums.net/threads/different-type-of-1171-omega-speedmaster-bracelet.52179/
Couple of notes on that thread; Novolink wasnt for Speedmasters but was for Seamaster Cosmic models delivered to Japan I believe. Also, 1171/1 wasnt only a service bracelet but was sold w/new Speedmasters as well. But not on a -71 thats for sure, it would be a service bracelet on that model

I have a 1997 145.022 and really like the older bracelets. Would a 1175 bracelet & 640 endlinks fit correctly?

If it's a 1997 Speedmaster Professional, wouldn't it be 3570.50?
At any rate, both the 145.022 and 3570.50 have 20mm between lugs, so I think the 1175/640 will fit.

By the way, my 145.022-71 with 1175/640 looks like this.

So after some searching, I decided to go with the 1175/640. Found a nice authentic one on eBay at a reasonable price with a 1971 date stamp. Definitely more durable than a 1039 and less “tinny” than the 1171. Watch looks great with it!
