    Hello. I wonder if someone can tell me how the Naiad-locked caseback works in the new Omega-models? I know what is the purpose of it, but wonder how it works. Is there a some kind of special gasget which should be replaced every time the caseback is opened?
    regards, Tapio

    Hi ,Omega new system of locking the case back to ensure that all the engravings on the rear of the watch stay oriented correctly – they call it a ceramic Naiad locking system -basically it's for a locking system for a screw-down case back that allows you to orient decorative elements on the case back, such as engravings, in proper alignment without having to match a given case back to a given case. The word "naiad" comes from the Greek and refers to mythological water spirits.

    Years ago they had a naiad system in the 50’s? To denote better resistance, hence the old naiad crowns on some models.

    Kind of like a camera lens mount is how I pictured it.
    Not sure about the gaskets.

    My new Seamaster has this case back but the words on the back are not aligned to anything. In fact looking at other seamasters, the writings are all over the place. Not consistent at all.

    (Edit: Not all of) the 300ms don't have a Naiad Caseback. Only watches with the "Naiad Lock" etching have it.

    Not strictly true. Yes the SS models don’t have it but the ceramic/titanium no-date version does.

    This is a bit of confusion with the Naiad term. The original Naiad was a water pressure based crown sealing system (picture attached) which some have said might not always have been as good at shallow depths (lower pressure). Irrespective they moved to screw in crowns. They have reintroduced the Naiad term as a case lock on a lot of the new releases as you have highlighted above (picture below) - like the deep black so that case back always lines up. This re-issue 60th Trinity Seamaster 300 crown still has a Naiad (Mercedes style) symbol as it is a 100% scanned replica (picture also below) ….. with of course a modern sealing system (screw down crown on this one now).

    Not confusing at all really. Just go on the Omega website and look at the SMP 300m range.
