Had some fun doing a complete service on a 16520 with the infamous modified Zenith movement, calibre 4030.

Took a few pics along the way, not really in chronological order, but wanted to share this cool watch with you guys

JayHantz · 1 February 2020, 06:19 AM

Bas, those are some great shots; I love the dial at the end. Anything you like about the Zenith movement that the 4130 doesn't have?

101031-28 · 1 February 2020, 06:19 AM

My absolute favorite Daytona, thank you sharing Ba, you rock! PS The picture of the movement with inverted 6 dial on the holder, is now my computer screen saver and iphone wallpaper!

TheGuvna · 1 February 2020, 06:37 AM

What a stunning watch and some awesome pictures. Thanks for sharing!

raclaims · 1 February 2020, 06:50 AM

That's awesome...my first Rolex was a Daytona I bought in 1998...never seen the inside of it though!

JoseR · 1 February 2020, 06:54 AM

Bas, thanks for sharing. Nice pics..

Thanks for posting great pics and details.

This is truly great stuff. Obviously, don’t understand much of how these little machines work, but these posts make me truly appreciate what I’m wearing

Onequik135i · 1 February 2020, 07:14 AM

Awesome detailed photos as always Bas, I love reading your posts.

rmlovett1 · 1 February 2020, 07:17 AM

very cool! Thank you

jaisonline · 1 February 2020, 07:18 AM

Bas,

this is AWESOME. perfect timing also as my 16520 is at the Dallas RSC for an overhaul.

thank you for posting the pics.

is the 4030 service much more effort than a 4130 due to having more parts?

sensui · 1 February 2020, 08:07 AM

Beautiful.

037 · 1 February 2020, 08:46 AM

Awesome work, Bas. Thanks for sharing.

I see a marred screw head though!

Kostas · 1 February 2020, 09:31 AM

As always fascinating Bas

The 4030 is just completely different, it is a very traditional architecture for a chronograph

I wouldn't say more effort. But Rolex classifies it as a 'classic watch' and therefore the service starts at €1150 (€800 for a 4130), so it is significantly more expensive to service.

Lol yes, I had to replace about 90% of the screws due to damage from a previous watchmaker, the 4030 has so many different screws, you don't want to mix them up

It is OEM but a service hand, it is most certainly not the 16520 a collector is looking for...

Thanks for sharing. I didn’t know that RSC charges differently between 4030 and 4130. Definitely something to consider when acquiring a Daytona.

Ha, yeah, I figured you weren't the culprit. I guess the last watchmaker didn't think anyone else would see his work.

SearChart · 2 February 2020, 02:27 AM

Thanks a lot everyone!

I enjoy sharing these mechanical pieces of art with all of you

Some are just oblivious. You see damage on screws like this several times a week, sometimes even when the previous service was done by an RSC.

Trust me, if you do that during a Rolex training you will hear about it.

Maybe because I'm still young and have only done this for a few years is why I care, and when I'm old and close to retiring I will damage screws as well

Watchmakers never get old, they just lose more screws.
