Does anyone here bought a modern insert and experienced fading after prolonged usage? I hope i can get a new insert from RSC and it turn fuschia in years to come.

awesome stuff, thanks for the info!

Bravo it's true you learn something new everyday thanks!:clap:

Best thread yet bravo!:clap:

Dear John,

I just want to record my sincere appreciation for such a informative sharing unselfishly. Thanks so much for enabling me to better . the finer things about GMT bezels. Thank you

This post is stressing me out! :banghead:

Can somebody assist in authenticating this please.

I think springer already pointed out not genuine.

Do you have the link to the thread?

really you have the link to the thread?

What's the problem? Are you shopping for someone to tell you it is genuine?

As I commented in your thread on this insert, it is fake and someone has also artificially bleached it. These fake inserts are sold on ebay.

A lot of work went into the first post. Thanks for the effort.

The prices on genuine inserts is fast becoming absurd nowadays. I hope mine never falls out, I would hate to try and replace it.

Thanks springer, appreciate your feedback on this. How are you with vintage 5513? Posted another thread for comments on it.

Anyone care to comment about the authenticity/originality of this insert/dial? '68 1675https://uploads.tapatalk-cdn.com/201...9135889005.jpg

Can anyone tell me what year the blueback inserts first appeared? They were never standard issue for 1675s, correct? Only as service, and then later standard issue for 16750. Do I have that right?

GMT 1675s all had red backs with red backs continuing through the end of the matte-dialed 16750s. It might be possible to find late 16750 mattes with blue backs - I can't say for sure - but, based on my experience, 1984 seems to be the time frame for the arrival of the blue backs with some time for transition between the two.

Slightly heartbroken now after taking out the insert on my 1675 and seeing a blue back. Lol.

great thread. thanks for creating it and sharing your knowledge

do replacement 16170 and 16170 inserts from a RSC or from ADs w/ a Rolex parts account come with a little scan code on the back? code looks like a smaller version of this package's code i found on google.

What’s remarkable is that some of the true fat font blue backs are so close to their red back cousins. Darn hard to tell without flipping them around. I wonder if anyone has done a detailed study comparison of red back to blue back fat font inserts ? I didn’t find one searching the site.

Yes. :thumbsup:

many thanks.

Just want to thank you guys a lot for the post and information shared !!
Very instructive and interesting.
:thumbsup:.

I need a cool pre-used Rolex with blue black inserts

Thanks for the info Springer.

Hi! My first post on this great forum :)

Thanks for a really great and informative post!

I just bought my first rolex, a 16710 from 2004. Really happy about it. Didn't know about these aftermarket insert thought.
Mine has a coke, and my conclusion is that it must be a aftermarket insert, correct? The 2's are hooked.
But I went by my AD and looked at a pepsi insert and it doesn't have the hooked 2's. But still I belive it is regarded as a service insert and not original/genuine anyway...?
Might need to dive deep and look for a original pepsi insert I guess

Picture of my in 1978 personally purchased, serial nr. 5.3XX.XXX 1675 with it's original insert (watch has cpl original parts, never anything changed, I have all doc's and purchase invoice of $ 525,-).

GMT 16710 is a great choice for your first watch - superb in every way. Enjoy!

Interesting

FYI...

Some folks are buying legit 16610 and 16710 inserts on the secondary market (sealed in the Rolex blister, loose, used, new w/o the blister) and the fit seems to be off. The insert just don’t fit into the bezel no matter how much you push with your thumbs (ouch). Sometimes you need extra help like carefully using good plastic pliers. I was able to get many of my inserts to work with ample electrical tape wrapped around my rectangular metal pliers.

Obviously this can make some people to think the insert might be a reproduction despite looking perfect (colors, numbers, rear bezel lips, etc...). Apparently like dial fonts, Rolex does make subtle changes with inserts (not just the front #s).

Take a look at this 2014 topic that helped me. Some really good info in it. In summary, some inserts especially the 16710 Red/ Black seems or be harder to install (mine was new in the blister). I also found new / sealed Root Beers to be difficult.

Good luck. Special thanks to @Jocke and @Rikki posting in the topic linked above.

Clearly, you are the expert in this matter Springer. I am curious what you think of this listing which advertises this insert as 100% original https://www.chrono-shop.net/en/1297-...750-brown.html. I have no interest in purchasing it but it looks like it could be another type of reproduction to add to your set. The fonts look quite small but correct What sticks out to me are the alignment issues with the numbers. Numbers to the left of 12:00 are aligned to the outer edge of the insert, while those on the right are aligned to the inner edge of the insert. I find it hard to believe this is legit and could pass quality control given real examples I have seen—even when compared to the pictures directly below where it says 1000% Guaranteed Genuine!
