Difference between original 3135 movement and 3135 in the Deep Sea?

[Badfish179]

Does anyone know the difference between the 3135 movement that is in say a 16613 and the 3135 in the Deep Sea? Thanks in advance for your responses.

A 3135 is a 3135 the world around. If it was different, it wouldn't be called a 3135...

However, Rolex has begun fitting the in-house Parachrom hairspring in the later Subs and Deep Sea models rather than the FAR Nivarox hairspring; so they have a different brand-name part there. Still, it is the exact same movement...

Thanks Kanger and Tools. I'm grateful for your response. I wondered about the hairspring. I didn't know if that made a huge difference or not.

Here is a nice overview of the blue hairspring. I don't know how much diff it really makes but my Deepsea is the most accurate Rolex I've ever owned.

Interesting reading, next time a Rolex hater says the common:"There's no reason Rolex watches are as expensive as they are, it's all hype..." you can point out the process of just one tiny part's construction. Not to mention the years of R&D and investments in tooling.
