What's the orientation of your seamonster caseback?

Mine seems to be perfectly oriented vertically. Is yours oriented or at an angle relative to the face of the watch or does it match up?

I ask because I'm writing a review for another watch and one of the features is that the screw caseback is specifically designed to orientate itself perfectly when closed properly.

At the risk of seeming facetious: it really depends how tightly I tighten it. I guess that, as there is a single screw-thread, if you were screwing onto a fresh gasket you could position it in most positions if you didn't mind compromising the depth rating. My guess is that Omega would have a uniform threading process and that they would thus set it up so that close to perfect torque would occur with the back correctly oriented. The head of my beastie is pointing to eight o'clock and was waterproof in this position at 18 metres a while back.

the orientation of the caseback has nothing to do with the "tightness" of the caseback. the orientation differs because of how the threads were cut. it's extremely difficult to control that type of an operation, even with CNC machinery. add to that you have threads cut into the case and the caseback and i'm sure you will find an infinite number of orientations.

My 42mm has the head of the monster aligned almost exactly with the HEV at 51-52.

Hang on, I'll just check that with reality...

Oh damn, that should read: inverted less tight case.

Either way, it looks like my caseback lines up perfectly now. As I said:

I think it has something to do with the compressibility of the silicone rubber seal.

As for CNC not being able to control for a particular position, well I know I can with a simple 1960's tap and die set (and I'm rubbish) so I really don't think it would be too much of a problem for Omega.

touche. let's assume that omega tightens the casebacks to a set torque value or number of turns. that said, I think the variations in hippocampus orientation are dependant on threads.

you working in your garage with a tap and die set vs. mass production are different things. you aren't cutting threads on hundreds of thousands of casebacks and cases each year.

Ok, you caught me out, I didn't loosen the caseback, I recut the threads instead. :-d

As it happens, I agree that they will tighten to a set torque, however the idea that this always gives the same orientation (relative to the thread) seems uncertain as there are quite a few variables here, not least the compression of the gasket and temperature.

However, I am certain that a modern computer controlled system can set a thread to start wherever they want it to - if it matters enough. I may not be cutting large numbers, but I also don't have the technology and experience of Swatch group.

The real question is: does orientation actually matter enough to Omega. I suspect not.

ahem...

its with threads, its possible but realy additional work and time, which most companys are avoiding because of the cost.

Here's the reason why I asked. The Kazimon DREI was designed so that every watch lined up perfectly and it's supposed to tighten back down to this position as well with fresh gaskets. It's an intereting design concept and a nice finishing touch. The caseback does require a special tool from Kazimon to open, it's usually included. I'll be doing a full review on it later on next week.

Is it a friction fit? Meaning no threads, it locks, or torques down into place with tongue and grooves? It just does not seem possible to me to ALWAYS line up perfectly with threads. I am not saying it is not possible, it is just not something I expect with threads, but I can understand with other methods. But I am open to be pleasantly surprised if the designer has made a control method with threads that works! :D (I guess the caseback could be designed to bottom out on the case at a maximum point of torque, no matter the gasket used...)
