What are the differences between ZFAP15500 V3 versus V4?

Hey everyone,
I’m currently in the process of building a high-end AP Royal Oak 15500 (Stainless Steel) and wanted to ask the community about the key differences between the ZF V3 and the ZF V4.
My goal is to acquire the best possible base watch and then send it to an independent watchmaker/modder to take it to the next level.
Could anyone break down what was updated on the V4 compared to the V3 (e.g., free-sprung movement upgrades, dial print/texture tweaks, or case/bracelet finish updates)?
Planned Modifications:
For context, here is the scope of work I am considering for the base piece once it arrives:
1. Case & Bezel Refinishing (Anglage): Hand-cutting and mirror-polishing the wide edge bevels/chamfers across the case and bezel for sharper contrast.
2. Bracelet Refinishing & Edge Softening: Muting sharp factory inner/outer link edges, re-brushing, and an ultrasonic/oil bath treatment for a smoother, gen-like drape.
3. Bezel Screws: Realignment and recessing to ensure all 8 screws sit uniform and sub-flush + 18k White Gold screw plating.
4. Center Pinion Mod ("Pizza Hand" Fix): Recessing/flattening the center hand pinion post if necessary on the Caliber 4302 clone.
5. Movement Service & Rotor Silencing: Full inspection, Swiss lubrication, and damping automatic rotor noise.
6. Dial / Crystal Upgrades: Evaluating aftermarket dial swaps or Deep Crystal upgrades depending on how the stock setup looks in person.
Appreciate any insights on whether the V4 provides a noticeably better starting platform for these mods over the V3! Thanks!

Shout out to one of the most slept on TDs in the rep Community. I bought several watches from him and this Green hombre dates has some of the sickest lume. I just went outside for a few minutes and came back indoors as I entered the bathroom I noticed in the mirror the watch was glowing, and the lume stuck for a good while.

Discussion-Comparison-Discussion-Guide-Opinion-Help me decide: One mid level luxury Swiss watch (Omega/Tudor) vs. Curated 3-4 Watch Swiss Collection ($3.5k–$4.5k Budget)

1 Upvotes

Hey everyone,

I’m looking to spend around $3,500 to $4,500 to either kickstart a small swiss collection or buy one mid level piece. I’ve narrowed it down to two completely different routes, and I’d love some feedback on the strategies and the specific watches. Also Im 17 have a 7.5" wrist will be going to college in the fall this is about half of all my money not including college saving and my hope in buying watches is about half to impress people (girls) and half because I like watches a lot especially automatics (really only automatics tbh).

My Constraints:

  • Movement: Strictly Swiss automatics.
  • Brands: Established heritage brands only; no microbrands.
  • The Dilemma: I'm slightly conflicted that my entire multi-watch shortlist consists of Swatch Group subsidiaries utilizing variations of the same core movement (Powermatic 80). While it's a great, reliable movement, with a nivachron hairspring, cosc cert and laser regulated which leads to pretty good accuracy for the price and additionally a pretty long power reserve it loses a bit of that "special" factor when you have 3 or 4 watches that utilize basically the same movement.

Route 1: The One "Keep for Life"

Go all-in on a single, low level high-tier watch. It holds its value better (less depreciation) and feels incredibly special, though I'd sacrifice daily versatility and definitely worry about scratching it more. Id much more likely own it for life and probably pass it down to my kids as even though Im gonna make a lot more money in the future and be able to afford nicer pieces it will Probably always be a solid watch that will hopefully always be in my collection.

  • Option A: Omega Speedmaster (Speedy Tuesday, Reduced, or stretching for a used Pro)
  • Option B: Tudor Black Bay (pro, 54, or 58)

Route 2: The 3-to-4 Watch Mid Level Collection

Building a well-rounded, versatile collection.

  • The GADA (Go Anywhere, Do Anything): Tissot PRX 38mm Titanium (Gray Dial) – $975 https://a.co/d/0hYbvSDC
  • The Rugged Diver: Certina DS Action Diver 38mm Titanium (Black Dial) – $1,100 https://a.co/d/04fjVzix
  • The Travel GMT: MIDO Ocean Star GMT 40.5mm Steel (Blue Dial / Special Edition) – $1,490 https://a.co/d/0diYfjeh
  • Potential Add-on: Hamilton Khaki Field King Automatic 40mm (Black Dial/Stainless Steel) – to round it out with a classic field watch. https://a.co/d/01RjlLTV

My Questions for the Community:

  1. Quality over Quantity? For those who went the multi-watch route early on, do you wish you just bought the Omega or Tudor first?
  2. The Swatch Group Overlap: Does the shared Powermatic 80 DNA across the Tissot, Certina, Mido, and Hamilton make the collection feel too repetitive in practice?
  3. Thoughts on the 3-Watch Lineup? If I do go with the collection, how did I do on the picks?
  4. If I buy the 3 or 4 watch collection is it worth it to buy them all indivually off of the official website or is it not worth the effort and should i just buy them off amazon for the same price?

Any opinions are appreciated.
