This pic was on reddit today... just curious if it's obvious to you guys what bracelet he's wearing with his Speedy?

 

Is it a 1039?

 

That's not a 1039, or a vintage Speedmaster. I think it's a Solar Impulse HB-SIA GMT

Indeed! Well spotted! Thanks

 

I have just bought one of these with the ti bracelet cost me sub 5k ,and have noticed that they are not widely discussed on here?

 

As recently (February 2019) worn by Apollo 15 CMP Al Worden:

 

Unless Buzz's bracelet is badly worn it appears there is far more space between links than the one in your image.
I blew the image up by 400% and there's quite a bit of space between the links. There's also no sign of the darker border of the center links. Perhaps earlier production variant?

 

I didn't make any claims about the bracelet itself (only that the watch appears to be an HB-SIA) but I think you're right about it, it looks like an oyster-style bracelet from the pic. I suppose could be an 1168 but doubt he'd have gotten one of those and put it on the HB-SIA. I'll bet aftermarket

 

Could be he already had a watch with that band and found it well worn in and comfortable so he had it put on a newer watch.
