Detailed Comparison Between Authentic Tudor Black Bay and Top-Grade ZF Replica. On the right side of the screen is the ZF, and on the left is the authentic version.

ZF conducts a detailed comparison with the genuine version, completely replicating the original data.
The details of the dial text have reached a level that is almost indistinguishable from the authentic version.
The shape and size of the hands are virtually identical to the genuine ones.
The watch hands have been modified and refined numerous times, resulting in a smooth, thick, and glossy finish.
Even the luminous powder filling is exactly the same in both area and texture.
The edges of the watch hands are finely polished with no burrs, giving off a high-end appearance throughout.

ZF’s case brushing and polishing are exquisitely detailed, giving off the texture of the genuine piece.
The thickness closely matches the authentic version. The crown features a clearly defined three-dimensional Tudor rose logo engraving.
The anti-slip gear pattern has smooth and refined edges, offering a handling feel identical to the original.

Reproducing the classic sandblasted bezel color combination is an immense challenge.
ZF has conducted in-depth research into the anodized aluminum two-tone coloring process.
The bezel matches the authentic version perfectly with no color deviation.
The black is deep and premium, and the red is vibrant yet elegant, flawlessly recreating the essence of the original.
It’s almost as if it were made from the same mold as the genuine product.

ZF Factory maintains strict control over every detail without any sloppiness.
The engraving and lettering on the caseback — whether deep or shallow, coarse or fine —
are all faithfully reproduced to match the genuine version 100%.

The casebacks are nearly identical — even when placed side by side, it’s hard to tell the genuine from the replica.
ZF has replicated the engravings on the lugs exactly the same as the authentic version.
