GMT Bezel Inserts, Aftermarket Inserts and Bleached Inserts

[TheWatchCollection]

I recently purchased this super fat font 1675 insert. But now I'm having doubts after seeing this. Can someone help me out? Is this an aftermarket as well?

I'm fairly new to GMTs, and I'm trying to learn as much as I can.

I've noticed that some of the experts here can tell whether a 1675/16750 insert is a red back or a blue back based only on the look of the front of the insert. Is that correct? If so, can someone explain the identifying differences between the two?

Also, I've tried to observe the points on the inserts where the blue changes to red. The crossover point is not always the same area for the 6s and 18s. That can be seen in the picture of all of the genuine inserts Springer posted above in his original post. Is that an important place to pay attention? Or just noise?

Thanks for sharing your knowledge!

The purpose of the thread was to help others identify the differences between the acrylic crystal inserts and the sapphire inserts along with some identification for aftermarket and bleached inserts.

Identifying every nuance of the numbers and differences between the GMT inserts would be the subject of a completely different topic and thread which I really didn't want to address in this thread. As far as the crossover point regarding where the red and blue colors split between the numbers 6 and 18 is not significant in my opinion and was probably based on when and where the inserts were placed in the stamping machines during the time periods they were stamped. I have observed this phenomenon and could never discern any significant difference in the number fonts regarding how this would reflect on where the color split occurred in relation to the era when the insert was used. In a "nutshell," I don't believe the location where the red and blue split occurs is significant to determining the age of the insert.

Plus they probably had a loupe or a magnifying glass out as well looking at those 2s and 4s!! Great reference material here for sure.

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.

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 1675
