Nice! Wearing my Gen 1 with same strap right now.

Just a quick update and some iPhone snaps... Mine is now back from service and looking good... it got a new movement/module (in addition to a new crown and one pusher plus the other testing/shoring up they do), but I don't know if it's the thermocompensated one! Not a big deal, just curious. Comforting to know now this will run solid for years to come.

Cheers,

I don't know if it will be the same for your watch, but before I sent my Gen2 in for service the backlight was definitely blue. When it came back with a confirmed Cal. 1666D thermocompensated replacement movement, the backlight is now green.

So, if your backlight used to be blue, but is now green, you probably have the TC movement. ;-)

I saw your post on that, glad it worked out for you!

Thanks very much, hadn't heard that one before. Here's a before/after comparison on mine, look like yours?:

Before service:

After service:

I didn't even realize that they were putting those in the X-33s! Mine went in for service about a year and a half ago and it's a green backlight!

Well ... the two "After service" pics look like blue on the left and green on the right. Mine looks like the one on the right - definitely green and not the very distinctive blue it was before service.

This was just posted on reddit /r/watches. It's a repair done on an X-33 while aboard the International Space Station. Thought you guys might enjoy it.

I want to be very careful with my comments. I know for sure that mine has the Cal. 1666D TC movement and that it has a green backlight now, but had a blue backlight with the old movement.

I do NOT know whether the Cal. 1666D TC movement is the ONLY movement version with a green backlight. So I cannot make the statement that a green backlight is a definitive descriminator for the Cal. 1666D TC movement.

Sure, I understand. If I remember correctly, there's not actually any marking on the movement itself specifying the version. So I suppose there's not really any way for me to know. I'll keep doing research to see if there's a better way to distinguish versions.

Mine's getting a full service at the NYC Boutique here and I'll get the watch hopefully back this week or next and can bring light to the TC movement (if they replaced mine).

 

[ASRSPR]

Actually, gaijin (or anyone else with a confirmed 1666D) - could you see if the movement is marked as such or just simply as "1666"? I seem to recall that mine was the latter.

I'm in no hurry to open up my freshly serviced watch ... but will definitely take a picture during the next battery change (or if my patience runs out, when I calibrate the movement ;-)).

[IAMsterdam]

I'll add some close-ups to change it up a bit

 

[gaijin]

Close-ups are good ...

I like mine even more now that it's back from service with a new Cal. 1666D Thermo-compensated movement:

TC X-33? I must have been under a rock, in the desert...

P.S. I did end up with another X-33. This one I found in Bahrain at an AD. It is a Gen 1 that had been in their inventory since 1998. Same strap that you have in your pic, ( I really like that strap) but it was falling apart with age. I picked it up at a VERY good price, AND I have a factory warranty too, since the watch is from an AD and sold as new. (But a TC movement now? CRAZY!)

Pics or it didn't happen right?

P.P.S. I just noticed that the warranty card has an RFID chip (I assume)... You can see the bubble/bump under the 'do not throw away' symbol. How cool is that? (The AD had to get me a new warranty card from Omega, so I got the card about five or six months after I purchased the watch.)

X33's are always cool. I'd like to own one someday.

I checked my movement last night - just marked "cal. 1666"

 

[gt0279a]

From the technical guide on Cousin UKs site they list versions A, B and C for cal. 1666

When I opened up my X-33 it's a cal. 1666B which is listed as a 'limited edition'. Weird as the B version is the same as the special 'Americas Cup' edition limited to 12.

 

[Zidane]

Steve - where do you see the letter reference on the movement? Mine is going to need a battery change soon so I'll check it out when I install the new battery.

James - congrats on the new X-33! That's an awesome find. I bought the same kevlar strap that you have on yours now but it came with black stitching...weird.

The Cal. 1666D TC movement was obviously released after November, 2009, which is the date of that Technical Guide. ;-)
