VS Factory Rolex Submariner 40mm vs 41mm Comparison

Comprehensive comparative analysis of Vs Factory Rolex Submariner 40Mm and 41Mm models: Case finishes, movement precision, dial details and production tolerances are examined in detail with Saat Detective expertise standards.

Don't worry! Today, I will show you step by step how to distinguish them at a glance from four main aspects: size, mechanism, details and feeling of use, and I will tell you which one you can buy by closing your eyes right now.

1. The most obvious difference: Is there a “small crown” at position 6 or not?

This is the fastest way to distinguish the second and third generation:
Second generation 40 black ghost: 6 positions of the dial are clean, without any markings; follows the classic lines of the old Submariner.
Third generation 41 black water ghost: a small crown logo has been added at position 6; It exactly reflects the new Rolex design released after 2023, is more easily recognized and gives a more "new model" feeling.
Do not underestimate this small detail; It directly determines whether you carry a “classic model” or a “modern model” on your arm.

2. Size growth: Today's mainstream is 41mm

Although the difference is only 1 mm, the third generation has a case diameter of 41 mm and the second generation has a case diameter of 40 mm. Although the numbers look close to each other, the feeling is completely different when worn on the wrist:
The third generation's case, lugs, strap and buckle have been completely remoulded; not a simple enlargement.
Strap wider, links thicker; It is visually more assertive, and suits especially those with thick wrists or those who like the modern large watch style.
Although both of the buckles have a one-touch spring mechanism and a micro-adjustment feature, their internal structures are not compatible; Definitely do not use them interchangeably.
The difference may not seem big to the naked eye, but when mounted on the wrist, the fit and impressiveness of the third generation is noticeably stronger.

3. Major movement upgrade: 3235 vs 3135, the difference is not small at all

If the appearance is the “outward appearance”, the mechanism is the “inner value”. The real leap of this generation VS is entirely hidden in the Dandong 3235 complete movement.

In short: The third generation's mechanism has a longer power reserve and is adjusted more intelligently; Even the internal details are closer to the logic of the original. This is truly a technical upgrade.

4. Detail processing: VS solid as always

Whether it is the second generation or the third generation, VS never slacks off in its workmanship:
Hour and minute hands: Three-dimensional “Breguet” type design, no burrs on the edges, lume-filled and homogeneous.
Central spindle: The small, solid head structure gives a solid feeling in the hand.
Hour markers: The corners of the inverted triangles at the 6 and 9 positions are rounded, unobtrusive.
Crown: Embossed logo and polished corners, screwing is fluent.
Case and strap: 904L steel and fine brushing, scratch and corrosion resistant.
Buckle: One-piece casting, no welding points, micro-adjustment feature; It can be easily adjusted even with a diving suit.
Glass: In the third generation, completely transparent IO coated sapphire glass is used, there is no white ring around the edges, it is clear from all angles; The date font is oil print, the thickness is consistent and there is no chromatic aberration.

Especially the glass of the third generation is made with a concave curve design; It remains slightly above the ceramic bezel but does not protrude too much, giving a layered appearance and a high-end feel.

5. Which one to buy now? Summary in one sentence

Choose the second generation 40 black water ghost: If you love the classic simplicity of the old Submariner, are on a tight budget and are not interested in features such as 70 hours of power reserve and rewind date, it is still a reliable choice.
Close your eyes and buy the third generation 41 black water ghost: If you want a replica watch that will not become outdated after three years, whose mechanism is solid, whose details are meticulous and are closer to the new Rolex, the third generation is currently the ceiling point.
Particular attention: The so-called “Clean stock” products on the market are basically a marketing gimmick; The high quality black water ghost you can buy now is actually the VS third generation 3235 version. Look for the small crown at position 6, 41 mm and the Dandong 3235 movement; so you don't fall into the trap.
