About Original GMT Bezel Inserts: Dimensions n Features..++

Err...for the TRF Buddies...
Orchi wishes to to show these MODERN variants of...
the Original GMT Bezel Inserts...
that basically could be categorized by 2 types...

BOTH of which are for the early Plastic GMT...
n the later model of Sapphire GMT watches...

1. Ref 1675(1675/3)..16750/1675x...(Plastic Crystal).
2. Ref 16760/16700...16710/1671x...(Sapphire Crystal).

Orchi wishes to share the following in here...
with the TRF Buddies...

Thanks for watching n commenting...

Best regards
Orchi.


Lets begin with these 3 variants of bezel inserts...
seen to be with THINNER Fonts...
which could normally be found...
on 1675(1675/3) with >5mil Case Series...
OR...possibly being RSC Service Replacement part...

1. Ref 1675(1675/3)..16750/1675x...(Plastic Crystal).

Physical Dimensions:

Overall Outer Diameter....... = 37.7mm (+-)
Internal Diameter............ = 30.0mm (+-)
Width........................ = 7.7mm (+-)
Thickness.................... = 0.6mm (+-)










Some MACRO Scans to show...
Frontal PAINT characteristic(Metallic)...for BI-Colour shades.
Frontal PAINT characteristic(Silver/Gold/Brown Metallic)...for Fonts.
Paint surface consist of Tiny Dimples...NOT entirely smooth.

The Gap between "1" n "8" in "18" fonts...
are WIDER(broader) than the Gap between the fonts of "10/12/14/16"...






Frontal PAINT characteristic(Metallic)...for BI-Colour shades.
Frontal PAINT characteristic(Silver/Gold/Brown Metallic)...for Fonts.
For Gold Metalic Font of "6"...Border Split is NOT in Straight-Line...
Paint surface consist of Tiny Dimples...NOT entirely smooth.







Macro Shots - at the BACK of Bezel Insert...
with distinctive machine tool grooves.

PAINT in RED tone for 1675/16750...METALLIC.
PAINT in BLACK tone for All Black Insert...
(Possible in BLUE tone for 16750...METALLIC.)






2. Ref 16760/16700...16710/1671x...(Sapphire Crystal).

Physical Dimensions:

Overall Outer Diameter....... = 37.5mm (+-)

[img]http://i234.photobucket.com/albums/ee129/orchipalar/DSC06692.jpg" alt="[linked image]">
(With Serif Fonts on "COKE"..."PEPSI" n All Black Bezel Inserts...
found on Early Sapphire Crystal GMT watches...)







Some MACRO Scans to show...
Frontal PAINT characteristic(Metallic)...for BI-Colour shades.
Frontal PAINT characteristic(Silver)...for Fonts.
Paint surface consist of Tiny Dimples...NOT entirely smooth.

The Gap between "1" n "8" in "18" fonts...
are Slightly WIDER(broader) than the Gap between the fonts of "10/12/14/16"...









MACRO Shots - taken from the BACK of Bezel Insert...
for Sapphire Crystal GMT watches...
with different levels of machine tool grooves.
The PAINT Color on Insert Back is usually in BLACK tone...only.

BUT Please take NOTE of the 4-Tiers Angled Machining Tool Grooves...

At the 4th Tier...there is the distinctive RIDGE...
which is present at the Base of the Bezel Insert...

This is totally different by comparison with the one that fits...
the Early Plastic Crystal GMT Ref 1675/16750...1675/3...16753.













TRF Buddies...please be wary of these Aftermarket ones...
They may look the same...
BUT they are NOT the same Original Rolex...

It also should be known that with regard to the Root Beer Insert (known to Rolex as Tigereye) comes in about 3-4 variants over the years. The example you have is the most desirable.

Brown and Bronze (above)
Brown and Champagne
Brown and Baby Poo Mustard Yellow ()

Orchi,

Thank you so much for your detailed posts and for sharing your research with us.

I struggled with the best place for this thread to be and thought information like this should be archived in the library where it might get more notice from those of us who are students of the brand.

Keep up the good work and thank you for sharing the fruits of your labor.

Hi Orchi,
Much thanks fr yr info which is very useful to us.
I just bought one GMT 16700 E series(1990).
I checked the overall condition is good and found the benzel is still so new after such old years. I wonder whether this benzel is a aftermarket on or its original one.
can you or somebody judge it through the pictures sent here?IMG_5484.jpg

I know this is an old thread, but I just had an insert with a so called top heavy 2 font (top right corner in the photo) verified by rsc in Singapore and they authenticated it as genuine.
So the statement that it's fake in one of the links posted by OP is not entirely true.

Orchi posted in 2010 the inlay of a 1675 GMT with the next characteristics:
The Gap between "1" n "8" in "18" fonts...
are WIDER(broader) than the Gap between the fonts of "10/12/14/16"...




*****
Below my 1978 - 1675 GMT (series 5.3xx.xxx) with original inlay of which the arrangement of the "1" n "8" in "18"fonts is extreme wide with a different / more balanced location of the dividing line between blue and red......




Moreover the "Orchi" dots can not fill the circle in the "6" and "16" entirely; whereas "my" dots fill these circles fully......
I see some more differences...... as the fatter numbers in my picture........etc.

REMARK / BTW: Orchi has a full Fat 4 (ref: 16610LV 2003 inlay) and I have a 1/2 Fat 4..........?

GMT Pepsi Bezel insert back colours

I wonder if anyone can explain the history of the GMT red/blue bezel insert backs. Why are some vintage inserts blue on the back and others red. Did they change from red to blue at a certain time or were they both manufactured during a certain period. Thanks so much. 🙏
