--Fitting the Forstner “President (1450) For Pre-2018 Omega Seamaster" to the Project 300 with Project 300 end links--
--- Howdy All,
A while back I mentioned in a post that I had mated the Forstner bracelet to the Original Equipment MKII endlinks for the
Project 300.
I also commented that I had taken some pictures, but was certain that they were on the 'big computer' back in Oregon....
- But, it turns out I still had the 'originals' on my phone...
......I
'Found' them earlier today when I was looking for something else.
(Old Age is Hell, folks....)
In the first photo I show basically what I needed for the ready-to-fit result. On the standard MKII
Project 300 bracelet, the screwed pin that fastens the end-link to the rest of the bracelet has a fairly small diameter.
The link on the end of the Forstner bracelet has a larger-diameter hole sized for the springbar-to-end-link-to-watch attachment.
So if we assemble this as it is, we end up with a very loose, sloppy connection that simply doesn't work.
What to do? How about a spacer tube to reduce the diameter of the hole so that the MKII screwed pin fits tightly and properly?
In the second photo, I show the tools I used for this project; a small Swiss pattern knife-file, used for cutting the tubing; another small, very fine-toothed Swiss pattern file for smoothing the cut ends and nicely smoothing any burrs, and a small pin vise that is sized to hold the tube that will be cut down to the proper dimension in order to fit inside the hole in the end of the Fostrner link, but also fit into the center recess on the MKII end-link, in turn allowing the small-diameter screwed pin to fit properly.
In picture 3, we can see the tube held in the pin vise, ready to measure the proper length in order to fit correctly. So what is the source of that tube? It is a spring bar that has had the pins and internal spring removed. It works out that the internal diameter was exactly the correct size to allow the MKII pin to fit through it properly. Actually, it was one of those "quick-release" spring bars that we see commonly supplied these days in a lot of straps. I don't use them, and the internals can be removed easily by twisting that little handle-knob off with a small pair of pliers.
In Picture 4, I had already cut off the portion with the window; then, cut to proper length, then clean up the rough ends with the fine file, and...
We end up with the spacer-tube we can see here in picture 5.
And there you are...ready to assemble with the screwed pin and some blue Lok-Tite, and after, fit to the watch case.
I really like the way the standard MKII end-links fit
(Perfectly!) in between the lugs on the
Project 300 watch case and really emphasize the shape of the lyre-lugs, and compared to the 'flatter-appearing' 'no-relief' links on the Forstner.
I just think this arrangement has a better appearance. As a bonus, it makes the bracelet effectively a bit longer also.
And now, a couple more photos of the result....
Thanks for 'watching'....
Best Wishes, and Enjoy Your Time....

Edited 01282023 -- (Added a photo and descriptive text)
Here is another photo of the parts laid out with the dimensions of the "spacer tube" included -
As I mentioned above, the "spacer-tube" is basically another spring bar that has had the 'guts removed' and the body cut to length in order to fit within the mating opening of the MKII OEM end link (next to the watch body). The pin shown is the screwed pin that fastens the MKII end link to the MKII bracelet... It all goes together nicely and the fit is comparable to the amount of play present in the Forstner bracelet links.


And, I can't pass up the opportunity to provide a couple more photos of this "fantastic mod"....
(IMHO)
I really think the shape and fit of the OEM MKII end link is superior to the one provided with the Forstner.... But the Forstner bracelet is very comfortable, and the profile of the links at the ends of the bracelet are a much more 'elegant' match-up to the watch case...(IMHO)
I mean, after all, the MKII end link was developed exclusively for the MKII watch case...
My Best to All...
