Please clarify your terminology. What is a wrist perimeter? Width? I think I know what you mean, but it is a bit unclear. You also mention watch width with lugs, so I assume you are talking about a 12-6 'length' measurement and not a 9-3 'width' measurement. Should crown width be considered? Put this into an Excel spreadsheet once we shore up the definitions.

Yep. Acquiring the service parts, and a 'serviced' 1575-GMT took over a year to pull together. With patience, I have saved about $2000 -vs- buying a 1675 outright, and then having to have it serviced. So a $2k savings, and the satisfaction of assembling it myself makes it well worth it. A grail piece for me. Put the movement on the watch timer, and it is keeping COSC!

Enjoy! Those that know me, know I like the minty NEW look, and a fresh chance to "Let it Age Naturally on my Wrist". Kicking off the project. Stay Tuned.

Another shallow cut like mine. At this point the WSO bezel is not an issue IMHO.

I picked up a Dunhill (rep) from KB.

I find it fascinating the 448 has a sterile dial. Nice line-up.

Excellent post. I poured over bezel photos for hours on VRF and elsewhere. My conclusions were: 1.) With Rolex, there is no hard and fast rules governing parts/replacement parts. 2.) I have found some examples of shallow bezel cuts that look almost spot on to WSO's shallow cut bezel. 2a) I also think shallow cut looking bezels could also be the result of wear and tear and/or polishing. 3.) Rolex GMT line, especially 1675's have the most variations of ANY Rolex Sport Model ever produced. Based on the following photo's what are your thoughts on these? Gen/Rep etc...

Considering we were in Switzerland, I would have at least expected Victorinox over Casio.

Same here, same here. Just saying if given the choice between a 100% perfect outward facing watch and a 0% perfect backside -vs- a 80% Perfect All Around, I would probably go for the former.

If you ever make it to Geneva, make sure you go to the Patek Museum! It was awesome. Security was crazy as you can imagine. Funny thing, most of the "Security Guys" (X-Military Looking) were wearing what looked like G-Shocks!!!

Short answer = Yes, on a non-complicated/no-date model like a 112/176. You will need to cut off the dial feet to rotate it 180' and use adhesive/dial-dots to re-affix it.

I fail to see why so many worry about the 'back side' of our reps. How often are you taking off your watch and handing it to some stranger. I would rather the visible side, when worn, be 100% perfect-- even if it meant these had sterile movements and/or casebacks. Just my .02.

That's not a watch timepiece, it is jewelry.

I agree with Freddy. Also, I have worked with a case that had pits, and looked worn. Guess what! It still was waterproof and cleaned up just fine. Fear not!

Excellent write up. This makes for some great reference material. Gotta love the date Mag on the 1680.

Honestly, if it is a Genuine Unitas/ETA 18k, I would take it over the faster beat Asian movements. I have two Gen 6497 slow beats that are rock solid and close to COSC.

Great shots. Those UN's look great!

Awesome! A Smaller/Modest Size Watch is the new black! 34/36mm could make a come back.

I have handed GENUINE Rolex's to friends with GEN 9315, 93150, 62150, and they ALL thought the watch was fake based on the GEN bracelet. There is a thread on TRF about the rattle of the GENS. Yes, GENS rattle too. I think this is hyper-sensitivity. Rolex bracelets are notoriously NOT the highest quality bracelets out there. Hell Seiko kicks their a$$ in the bracelet arena. You friend has a GOLD Daytona. GOLD is significantly heavier to begin with. So take his assessment with a grain of salt. I also own a GEN Omega that has a bracelet that consistently binds up. While there are no doubt crap REP bracelets out there, don't fret too much. If it looks good on your wrist, wear it well and don't hand it to people.

I have done tons of 1675 research lately, and based on my findings: ALL 1675 Bezel replacement parts appear to be coming from the SAME SOURCE/FACTORY. We are talking aftermarket to fit gen spec. So whether you use Yuki, WSO, Clarks, JK, Classic, JW chances are you will be getting the SAME thing. So choose based on price and local shipping if you have the choice. HTH

I use mine a TON... on my GEN's (non-A7750). I use mine as follows: Track my parking meter use. I live in a major city, so when the meter says I have 2:00, I hit start. Time airplane flights. Usually wheels up-wheels down, when the Capt. says "Our Flight Time will Be" (Gives me final Bathroom warning). Grilling. (i.e. Salmon 9 minutes (5min on skin, 4min flip side) At allergist. I get allergy shots and have to wait :20 then show them my arm. (Telemeter) Time distance of Thunderstorms (or Artillery) So, for me I use them. I also use my Dive Bezels for the same reasons often. As for "Military Use" pre-digital age, having a Telemeter instead of a Tachymeter had its advantages. Still might actually.

It all comes back to: "Buy the Seller, and Vet the Buyer". This is why I will NOT sell to members with no/low posts.

Depends on who you want protected. I posted in another thread, that more and more watch sales on the GEN forums are asking for Bank-Bank Wire Transfers. No (significant) fees, and all 'good faith' between buyer and seller. However, in our little "Hobby" I am not sure this is an option unless it is between true friends on the forum. The other option is PayPal "Money Owed / Gift". This makes it another 'good faith' transaction as there is no buyer protection. This is banned on some FS Forums, but I don't know why given it is really no different than a wire transfer, cash deal, or god forbid Western Union.

Boxes are an optional "Accessory" purchase. Usually +$50~$90. To set the time should be pretty obvious, open the lever on the CG, pull the crown out to its one and only position and turn. (This must be your first MANUAL wind watch???) You can wind the watch 'gently' until it comes to a stop ~ won't wind any further. My GEN 6497 usually take about 40 thumb/forefinger 180' turns, or about 20 full 360' rotations of the crown. Just go slow, and you will feel when it stops and cannot be wound further.
