Dear all While servicing a Lemania 1340, I wanted to use the chance to renew the main spring, although the original still seems fine. I assumed that the Lemania 1340 is the same as Omega’s 1040 and looked up the mainspring size here, URL: https://watchguy.co.uk/cgi-bin/mainsprings So I ordered GR2681X (1.10 x .135 x 460 x 12 Automatic) from CousinsUK. But now, the centre of the new one seems to have a larger diameter than the original. The barrel arbour will not fit unless I bend the main spring. Did I order the wrong main spring? Thanks
