I've been having a problem with the bracelet on my black bay 58 either not tight enough with a link in and at the tightest micro-adjust hole, or too tight with the link out and at the loosest micro hole. My DIY solution:
Put in the link so that you will have to use the tightest micro-adjust hole (I.e. the too loose configuration).
Cut a tiny piece of fabric (I used an old nato strap) and paste it on the inside of the clasp. The pictures will show you which part I'm referring to. I just use normal double sided tape so everything is reversible and there's no damage at all.
The position of the fabric is important. You don't want it too close to the clasp mechanism itself as it may hinder proper closure of the clasp. What I found best is if the fabric piece sits in between the two links as shown.
As you can see, it raises the bracelet up abit effectively shortening it's overall length. It does make the underside sit higher than normal, but it's well worth it to get that perfect fit.
Before you say that we shouldn't have to do this on a luxury watch, I know this is far from ideal, and Tudor should sell half links and/or have more than 3 microadjust holes, but I hope this helps someone out there who has the same problem as me. Beats whining about it in my opinion. Cheers!
