Shooting through/past the bracelet and clasp is a bit of a pain so I will probably do a swap to the leather strap later today and try to get some decent photos for you.

Something I have noticed though; these mirror polished surfaces pick up scratches pretty easily so that will be true also for the case back, which is at high risk if the watch is on the steel bracelet. Mine still has a small circular plastic protection disk on it to avoid such scratches. If you leave it like this there is a tendency for the case to stick to your wrist. I tried it without the protection disk and the effect was the same, probably because the case back is so highly polished. Conclusion: leave the protective disk in place!

 

Some caseback teasers for you @mikechi22

 

I was offered no 249 or 250 ..... where do you pic up yours

 

Wow! That is so cool! I was thinking the RM was going to be non-engraved, which I sort of thought, sucked! Thank you for brushing away that sense of impending disappointment!

 

Oxford Street Omega boutique. Yourself?

 

Hi! Pardon my lack of insight, but to what do these numbers refer?

 

The edition number of 3557 pieces.

 

Interesting! So, they provide a series number in addition to the watch's serial number? That's a nice additional perk. Is it engraved somewhere on the watch or indicated on a certificate? How does one know?

 

Indeed. And a tight fit between the lugs.

I suppose the next one will say "Speed"

 

I can confirm the 12.7mm from caseback to top of the crystal for the Railmaster. There is a difference though between the Railmaster and Seamaster crystals. The Railmaster has a curved edge and flat topped central zone, the Seamaster has one continuous curve from side to side.

Railmaster lug to lug height is 47.8mm

 

Look at my previous case back post 2nd image

 

Aha! It makes all the difference (a) wearing glasses and (b) switching to the laptop! Very cool that each piece is issued a number. Not sure I love how prominently it is carved on there, but better than the dial, by a league! Thanks for answering all these questions! But you're the belle of this ball!!

 

The one and only Boutique in north of Germany.... Hamburg.
Actually they got 5 pieces... or had 5 pieces.

 

I wanted a watch below 100 but oh well. I wonder where those ones were sent to.

 

I don't know where these numbers were sent to. There are definitely VIP customers that can choose their numbers....

 

Congratulations Dan, fantastic watch and gorgeous photo

 

Clearly, I am not one!

 

Thanks so much [emoji2] Hope all is well with you?

 

Everything is great for me too, since Thursday a new arrival in the family

 

Speedy Tuesday? (I'm embarrassed to inquire, of course...)
