I don't think it's any secret that the EP400 is among my list of favorites. Both of my El Primero powered Daytonas run non stop as my daily beaters. This caliber is a workhorse...

Vanilla scent strap... Crazy! But a nice touch... I would have never known had it not been for this thread.

Have fun, M! Wonder what watch you'll come home with this time....

Monday... Tuesday...

I gotta say... Those are some gorgeous Overseas... Beautiful work, ff!

Looks great! Nice job on the CG's!

Ahhhh... The PVD/Dirk is my official desk clock

This morning- This afternoon- Tomorrow- Tomorrow evening- Easter Sunday- Haven't worn a lot of these over the past few months, so I figure some are due for attention...

What price range? And modern or vintage? I know of a few sources... But pricing is high...

I've got this watch, but it's been modified... Case is EL (I believe)... Movement is a Swiss 2892 skeletonized... One of my faves...

Excellent work, vacuum! The lume job makes for a huge difference!

Planning on slipping into something more comfortable once I get home (t-minus 22 minutes)...

That's kinda why I asked Indeed... Projects are very much all about the thrill of the hunt. Once the hunt is done... Well... Then what? I only wear two of my projects post completion... All others just sit...

What's on the wrist for today? For today... It's a Royal Oak day...

Great pieces, Mr K! Indeed... It's hard to take apart a donor to build a watch... But, you absolutely have two fine specimens to show for it... So... How much wrist time do these bad boys get?

Actually, the difference I was trying to point out here was the size of the opening in the crown. The gen has a much larger inner diameter, whereas the rep has a smaller diameter (note the arrow pointing to a flat top surface at the base- The genuine crown doesn't have this, but rather angles/bevels in). Also... If you look closely at the threads, the difference in quality is very easy to see. The size of the shaft for the stem is different between the two because the tube diameters are different (on both O.D. and I.D.). The rep tube is smaller to match the rep crown having that smaller I.D. opening. Because of this, it is impossible to fit a gen crown onto a rep tube and hence why the pair has to be upgraded at once. I tried cleaning the pic up a bit to hopefully show this a little better. Since I'm at the office, I have to rely on the use of old pics instead of being able to snap new ones...

The vintage Triplock 703 (like this): Have been fitted to watches up until the early 90's, when they were phased out with the smaller coronet/tighter dot pattened crowns. So, that's why some 16520's have the same crown, while others don't. For what it's worth, RSC replaces with the new style small coronet version.

What can be said that hasn't been said before? This is a fantastic review... Excellent overview of the product- construction, quality and function all covered in great detail (I especially liked the review of the 'internals'). I do hope that you'll follow up with a long term review of this item... I'd certainly like to know how well this winder performs in the extended use category... Well done!

Happy birthday gang! Here's to many more...

A few more... As freddy333 pointed out, the coronet and triplock stampings on the exterior of the crown are more defined and sharp/precise- But, the other characteristics that will identify a genuine 703 Triplock are: 1) The opening of the crown where it fits over the tube- The genuine Triplock tube is quite large at the base diameter where the gasket sits. As such, the crown has to have an opening large enough to accomodate. This picture shows just how large the opening is- ***Note that the opening starts at the base of the bevel- Rep crowns use smaller diameter tubes and hence require a crown with a smaller diameter opening. You'd see the crown's bevel and then a flat edge at the base before the opening... Here is a comparison... See the difference? 2) The 'cut' of the ridges are much more defined on a genuine crown, and the profile is typically much shorter on the gen as well (rep crowns are too 'tall'). Compare these pics... In this pic, notice how flat the tops of the crown ridges are. Same watch (after mods)... Now with a gen crown- Nice, sharp, pointy ridges... And, as freddy mentioned, the feel of the crown is much better as well. Much smoother when unthreading from the tube... Much more confidence inspiring...

Why, Rolex does.... But of course! No substitute for a genuine insert. The pearl construction and the WG setting makes for a huge difference...

Some great watches gracing the wrists of RWGers... Keep em coming...

Movement looks like a 17j Chinese caliber of some sort...

Not sure that it would serve for anything more than novelty reasons. The majority of mechanical watches already have shock aborption at the balance (incabloc, KIF), which is usually sufficient for most activities.
