I was changing the micro adjustment and accidentally let the spring bar fly across the room. I was able to find it, but it made me realize I don't have a spare. Does anyone have the Omega part number for this spring bar?

I’m interested in this. It seems the 3862 needs different spring bars for a strap vs bracelet and are the microadjust ones different again?

Yes, the spring bar for the micro adjust is much smaller.
You definitely should use a 20mm spring bar for a strap. I had a NATO strap on mine a while back using the 19mm bar that came with the bracelet. I caught the strap on something and it pulled the spring bar loose. From what I have read, if you use a 20mm with the bracelet, it is extremely difficult to remove.

I've been using the original spring bar that came with the bracelet with natos and leather straps. Didn't know anything about this 19mm vs. 20mm bar thing you mentioned. Do you know if the 3861 version in strap comes with different spring bars?

Bracelet springbars are shorter than springbars used for NATO and leather straps. In the previous 1861 'suitcase' Speedmasters, which included a NATO strap, you were given a set of longer springbars for use with that strap. If Omega went through the trouble of including a longer set I think you should follow their guideline. I expect the strap version 3861 comes with longer springbars, it is just more secure.
