Spring bars Omega 18mm — single diameter
€12,95
Set of two Omega 18mm spring bars, in hardened Swiss Standard steel. Pin diameter: 1.8mm. Specific size for Omega dress models with narrow lugs: De Ville Prestige, Constellation Manhattan small, Seamaster Aqua Terra 36mm, some Globemaster ladies.
The 18mm Omega is less common than the 20mm/22mm sport sizes but represents an important segment of the dress line. 1.8mm pin — the Omega standard for all modern production, different from the 1.5mm Rolex and the 1.8mm Datejust. The difference is noticeable on an Omega case: the wider pin holds better in Omega lug holes, which have slightly different tolerances from the Rolex system.
The same spring bars I use on every 18mm Omega that comes through the atelier.

Frequently asked questions
Does this 18mm only fit Omega, or can I use it on other brands?
Technically, the 1.8mm pin diameter is Omega standard, but it also works on other brands with the same calibre of hole — Longines, TAG Heuer, some IWC have compatible recesses. The difference lies in the tolerances: on an Omega the 1.8mm pin holds perfectly, on other brands it might be slightly looser. I recommend measuring the hole on your case before forcing it.
What is the difference between the 1.8mm Omega pin and the 1.8mm Rolex Datejust pin?
Both are 1.8mm in diameter, but Omega holes have different tolerances from Rolex ones — ours are calibrated to seat the pin with a tighter fit. If you use these on a Rolex, the pin will go in but you will have slightly more play. Conversely, a Rolex pin on an Omega might be too tight.
Are they also suitable for sporty Omega watches 20/22mm, or only for dress watches?
No, this 18mm is specific to dress watches. Sporty Seamasters and Globemasters use 20mm or 22mm. If you have a 36mm dress Seamaster Aqua Terra (the vintage one with slim lugs), then yes; but modern 41mm Aqua Terras need the 20mm.
How do I know if my Omega needs exactly this 18mm?
Measure the distance between the two lugs on the case — if it's 18mm lug width, then you've found the right candidate. Then check the diameter of the lug hole: it should be 1.8mm. If the model is a De Ville, small Constellation Manhattan or Globemaster ladies, it's most likely the right size. If you're in doubt, send a close-up photo of the lugs.
