One of the most discussed topic regarding spring bars is which replacement spring bar should I get for the Speedmaster Professional or Seamaster Pro. Both lug widths are measured at 20mm which makes them share the same length. The best answer would be Omega spring bars which I highly recommend. However, one thing that most people don’t realise that the spring bars used are in two different sizes depending on your strap.
- 068ST2207 – Bracelets will be in 19mm spring bars
- 068ST2208 – Leather straps and rubbers will be in 20mm spring bars.
If you have the big box Speedmaster that comes with the bracelet and strap, the supplied spare spring bars are different sizes to the ones installed.
The code follows the same logic where you add a digit to go 1mm above. For example, a 22mm spring bar will be 068ST2210.
