50th Apollo 11 Bracelet on WatchCo Seamaster 300

Indeed it does fit and I am super pleased. When you're not wearing the watch, there is a bit of play but it snugs up when you put the watch on.

Please pardon the water spots; we have some rain/mist here today and I didn't notice before I took the pic.

Sweet, are those original Endlinks?

After many "tests" including the original 1039 , shark-mesh and isofrane, I found a lovely riveted bracelet (with a watch on it 😀) and bought both. Super comfortable now! Endlinks not original, I should do some "dremeling"-work one day..

Yes, and official Omega springbars.

Here's the Watchco Seamaster 300 on a Forstner 1450 bracelet with Forstner "Speedmaster Pre-2021" solid end links.

I tried an Omega OEM 1171 and Apollo 11 flat link bracelet, but I think I like the 1450 best.

The 1450 is the "Goldilocks" bracelet for the 300. The 1039 flat link style is too blingy with the polished links. 1171 is too cheap feeling -- rattling end links and poor clasp can't be centered and pops open on humid days.

The Forstner has a few spring links that stretch when your wrist swells.

Are there any other OEM clasps that fit the Forstner or Uncle Seiko besides the 1162?
