ubiquitous

Also depends on what the criteria is for a PO, as there are many different varieties. You have cheap, low cost, high end, high cost, quartz, automatic, 42mm, 45mm, strap variations, etc. There are some that are good for modification with gen parts, and then there are some that are 'good enough' out of the box. Might be a good idea to narrow down exactly what you want, and we can help point you in the right direction based on your preference...

Nice Bubbleback! Great condition! 1930's - 40's seems about right. Looks like it's in terrific condition considering it's age!

SC- The case used for that watch started as all rep. The only parts that I swapped out were the crown, tube and pushers. I should have probably changed out the crystal for him as well since it's a bit too low, but he didn't want to spend a ton of money on it. Most of what went into the project were items I already had and gave him. The only thing he had to pay for was the movement, dial and hands...

Well, in terms of using a 7750, I agree that the thin case used for the sec@6:00 116520 is the way to go. Here is a comparison of a thin profile 7750 seconds at 6:00 case with my El Primero case: 7750 case on top: And a couple of pics of the 116520 build I did for my Uncle (his watch has been long since dead, BTW): The profile of the mid-case is about the same, nice low profile/flat bezel and shallow rehaut, but the back of the case has a flange/lip that provides the height to allow fit of the movement. Since the height is added with the flange, the shape of the mid case body is more correct; on the wrist, you are less likely to notice the added height.

I admit- There have been times where, upon completing a project, I might post a feeler for trade, etc. This doesn't happen often, but when it does, it's usually cause I'm already bored and need a new project. As with any hobby, things only stay interesting as long as there's something to do

Personally, I just stick to what's comfortable If it wears nice on the wrist, isn't too top heavy and isn't so big that constant contact with door frames and table edges isn't a problem, and the lugs aren't overhanging my wrist, I'll likely be good to go. For what it's worth, I only have two 40mm pieces in the collection these days- One Rolex and one Tudor. The rest- A couple of Omega SM's and IWCs come in at 42mm each; my largest is my sole 44mm PAM. The smallest in my collection is my 36mm modded Royal Oak gents. To me, the profile of the case is really more of a driving factor. I loved my Breit Blacksteel, but proportionately, it was just way too tall/thick to really be comfortable for me. It's all about balance, but then again, I have slender wrists (6.8").

I only have one white dialed watch in the box... So, I guess that classifies it as a favorite?

Thanks for the kind words, one and all! I've really gotta say; if it weren't for Concepta sourcing the dial and hands, I think I might have had to resort to just buying the gen. I foresee this one going into heavy rotation, whereas the Daytona and the others might be seeing more of the watch box lid. I never realized how practical a day-date watch was until I started wearing some of these IWCs @delta- Looks like modelizer and Zig covered the question on this, but yes- The tubes on the hands are silver, and riveted to the hand. As Zig notes- Very functional, and it adds a nice finishing touch. The small details, eh? @techlogik- The day wheel is in German.

Have you visited your AD yet? If not... Take a trip down to the showroom. Look at the crowns on their Sport models. The solid, non-crimped crowns are not unique or exclusive to the 16622.

Consider that an EP400 is 6.5mm in profile, whereas a Valjoux 7753 is 7.9mm; 1.4mm doesn't seem like a lot, but when we're dealing with something as small as a watch case and movement, it will definitely add to the height of the case/case back. Also, the 7753 will not have the same subdial positions as the El Primero 400. The registers are positioned too far out towards the edge of the dial (an EP400 has the registers grouped fairly close together).

Looking good, fitchy! That case/dial combo kinda threw me for a loop when I saw that first pic; probably because I've only seen and known this particular piece with the PVD case. Even though I read Pre-A 2 in your topic, I wasn't quite prepared to see the steel case Funny how the mind plays these tricks Great looking piece and looking forward to seeing the 202/A when it's done!

3719 for today...

Excellent play by play, S! Job well done!

Well, considering that replacement bridges, plates etc. are easily swapped during servicing, etc. the provenance is not as easy to track. The mish mash of parts over the course of time can easily dilute the provenance of a piece, and you'd never have a really accurate picture of it's true origins anyways. Plus, think about the volume ETA churns out on these things. 30 years of production... That's a lot of records to keep for movements that are so... ubiquitous... in the world of horology, I'm sure they probably don't see much upside to maintaining or managing that kind of data.

From Silixprime you say? Very interesting...

See if you can get the beat/rate checked on a Vibrograf.

I checked mine last night- Crown feels pretty solid at the day/date setting, but at the time setting position it does feel a little wobbly.

Indeed. Ziggy has all the great toys in his shop!

How much time would you say it's gaining within a 1 hour/12 hour/ 24 hour time frame? Depending on the amount, it could be a rate/beat adjustment issue, or if it's gaining an egregious amount of time, it might be in need of an overhaul.

The title of this thread had the potential of being something very dirty Instead, I've come to find a menage a trois with 3 beautiful ROOs! That EoDBD is, I think, my favorite of the bunch!

Good reading indeed! I had to print this one off... Such articles are good for when spending time in the study...

ROFL! Yeah, I know... This thing has been back and forth from your door to mine so many times these past few months... I can't blame you, Zig! It's logged more air travel in the last 120 days than I've had in 6 years But don't worry... I don't think it has to come back any time soon! As for today's visitor; I don't think I have to worry too much about this one, as I think he has one of his own due sometime soon also But he has been asking me about my Snowflake lately

Ziggy lume all around. You can't beat that! Both look great! It's interesting to see the Cousteau and the smaller Slevin side by side. Pretty big difference when you see them compared in this manner!

Great work! Indeed- These are mods that most anyone can likely tackle. It does help to have the right tools, patience, a good understanding as to how these things go together, etc. but most of the time it's just a matter of diving in and getting your hands dirty. Probably the most aggravating mod on your list for many is getting the DW's lined up center for every date of the month, and making sure it's nice and level so that rubbing doesn't occur. Takes some time and practice... Definitely lots of trial and error! Still, there's nothing quite like the satisfaction of having done the job yourself

Very interesting to see the steps and process required to make something that most people would consider to be a very simple item. Definitely not as easy as one might assume the fabriaction of a pin to be! Nice work as always! It's neat to get an inside, behind the doors look at how this stuff is done!
