Speedmaster 3861 - correct OEM spring bars

Hi everyone,

I have some questions regarding the correct OEM spring bars for my Speedmaster Professional Moonwatch 3861.

As I read in the forum, Omega uses:

  • 19 mm spring bars for the steel bracelet (068ST2207)
  • 20 mm spring bars for leather/rubber/NATO straps (068ST2208)

I contacted my local Omega Boutique and received two types of spring bars, but I’m confused about what I got:

  • 068ST2208 - these are 20 mm long and straight. As far as I know, this is the correct part for straps.
  • 068ST2207 - this should be the correct part for the bracelet, but what I received were curved spring bars, which surprised me.

So my questions are:

  1. Is it correct that 068ST2207 refers to straight 19 mm spring bars or is this the part number for the curved spring bar?
  2. What exactly are the curved spring bars used for? I tried it with my Nato Strap and I quite liked the slightly different look.
  3. Can anyone confirm the official Omega part numbers for:
    • 19 mm straight spring bars (for the bracelet)
    • 20 mm straight spring bars (for straps)
    • Curved spring bars (if applicable)

Thanks in advance for your help!

Yes 2207 is a straight springbar (22,428mm) for 20mm bracelet and 2208 is also a straight springbar (23,317mm) for 20mm straps.

2206 is for 19mm bracelets.

Okay, thank you very much!
Then I think the OB must have mixed something up as I received a "curved" spring bar instead of the straight 2207 for the 20 mm bracelet.

Do you also know the number of the curved spring bar for 20 mm straps?
