I have heard various negative comments in the past about Scott Carpenter versions of the Cosmonaut
Do any of you have a knowledge of potential issues with a Scott C?
Seems the movement is high maint?
thanks

That makes absolutely no sense because there is nothing different about the movement in the Scott Carpenter version. It's the caliber 12 that is based on the Lemania 1873 / 1877 used in a huge number of Cossies and Omega Speedmasters.

I agree, but i have heard various rumors including the Scott C model has a plastic gear that wears out.
I am asking the question in general terms to see if there is any truth to the rumors or whether it is just a myth

I am thinking of buying a scott C
thanks

Breitling use a delrin brake in the caliber 12, which is actually a better part than the metal equivalent. Breitling will replace the delrin brake with a metal one in DB versions because some people think that the metal is more visually appealing, but I know of no issues. My DB still has the delrin brake.

According to Dupont:
Delrin® bridges the gap between metals and ordinary plastics with a unique combination of creep resistance, strength, stiffness, hardness, dimensional stability, toughness, fatigue resistance, solvent and fuel resistance, abrasion resistance, low wear and low friction.

Likes like some type of a Resin, so this may be what people blame for Scotty issues, according to you (and Dupont) it is not a problem

Like Roff said durability or functionality are not the issue, it's more one of aesthetics or peace of mind. In priciple the plastic should be more durable than metal but some people just don't like the thought of plastic being used and in the DB versions for some it is not eye pleasing.
Here's an example of a CAL 12 with the chrono Delrin Brake visible.

GREAT PICTURES!!! :!:

Why doesnt Breitling do more display backs....so cool!

I understand the part and i cant see this as being a systematic problem.
So, any other thoughts on the scotty?
If anyone has an idea what a fair price is for one on a bracelet, please PM me. I cant seem to find good market data.
I dont want to over pay..... :shock:

I only know of 5 models they did a display back.
Rare!!

I learn something new every day here. I would have never thought they would use Delrin as an actual part of the movement. I've only seen it used inside a case to hold a smaller movement in place. Very interesting choice of material. Delrin is used widely in prosthetic componentry, I just never new it was used for the brake mechanism.
Thanks for the information guys!
