Even still, the first generation of the Submariner 14060M also consisted of two-line dials, despite the updated movement. Likely due to the additional costs associated with submitting the movements for third-party testing, Rolex still seemed reluctant to submit the watch to the scrutiny of the COSC, and so the first Submariner 14060M watches were not officially qualified as chronometers.
It wasn’t until as recently as 2007 that the brand sought official chronometer-certification for its Submariner No-Date movements, leaving collectors with the choice when purchasing a Rolex Submariner ref. 14060M of going for a formally sanctioned four-line ‘
Superlative Chronometer‘ version or sticking with the cleaner dial and more vintage-inspired aesthetic offered by the older two-liner variety.
