ZF made a serious engineering compromise here. On the ZF version, even when the safety catch is flipped down into the locked position, pressing firmly on the main clasp body causes the whole assembly to pop open. That creates a genuine risk of the watch dropping off your wrist during everyday use.

When you stack up dial color fidelity, bezel texture, print accuracy, and bracelet safety mechanics side by side, M+ clearly takes the lead for the Tudor Black Bay Chrono range. ZF put out a decent early effort, but M+ simply put more care into resolving the trickier engineering details that matter to collectors on the wrist.
Bracelet Clasp Safety Mechanism Engineering
The last major checkpoint—and honestly one of the most critical for actual daily wear—is the folding clasp mechanism. Tudor designs their clasp with a strict mechanical interlocking safety latch.
On the genuine watch, you cannot release the main deployant blade without flipping open the outer safety lock first. M+ replicated this internal geometry flawlessly. When you snap the safety lever down, the main mechanism locks securely in place.

If you look closely at the profile shot above, the genuine crystal stands just a hair taller than the M+ sapphire. We are talking fractions of a millimeter here—something you will never notice while wearing the watch, but it is worth noting for complete accuracy.
Moving onto the tachymeter bezel, the anodized aluminum insert needs a subtle matte texture rather than a shiny gloss coat. M+ nailed the font weight and spacing across the scale.
On the flip side, ZF ran into a couple of execution problems with their bezel insert. The surface finish is way too smooth and reflective, and the lettering—particularly around the ‘UNITS PER HOUR’ text—looks stretched horizontally compared to the original font file.

Testing the date wheel cycling across a full month on the M+ piece, every single digit centers cleanly inside the frame. The font weight is thick and crisp, matching the raised ink printing style seen on the original dial.
Crystal Height Profiles and Bezel Engraving
Tudor uses a distinct domed sapphire crystal that creates a vintage box-shaped profile from the side view. Capturing that exact curve without introducing distortion along the edge requires proper crystal gasket sizing.

If you have been following my site for a while, you know I have covered a ton of releases from M+ factory. They built a solid reputation around the community for taking on tricky models from Bell & Ross, IWC, and Tudor, usually getting the finer details right where other makers slack off. Over the past few months, my inbox has been flooded with messages asking about the recent wave of Tudor Black Bay Chrono replicas—specifically the eye-catching Flamingo Blue dial version that everyone seems to be debating lately.
A quick trip down memory lane: BLS was actually the first factory to push out a rep for this chronograph line, followed closely by TW. However, neither of those early attempts really hit the mark on casing finish or dial printing. Today, the real battle comes down to ZF and M+ (also known as M+F). Back in August, I did a quick side-by-side comparison on the classic M79360N pandas, but today we are diving deep into the Flamingo Blue variant. I have the M+ piece, the ZF version, and a genuine watch right here on my workbench to see which factory actually got the small stuff right.
Current Market Availability for the M+ Tudor Chrono Series
Before we start tearing into the dial colors, it is worth pointing out that M+ has actually rolled out the full five-model lineup for the Black Bay Chrono range. Whether you are looking at the reverse panda, the champagne accents, or this light blue piece, they are all built on the same updated case geometry and bracelet setup.
Side by Side Dial Color and Paint Tone Accuracy
Matching a pastel shade like Tudor’s Flamingo Blue is a nightmare for replica makers. If the base primer is too thick or the lacquer mix is slightly off, the dial ends up looking like cheap painted plastic under natural sunlight. This is where most earlier factory runs failed miserably.
Laying the M+ piece (left) next to the gen (right), the shade matching is remarkably tight. Under direct daylight, the reflectivity and undertone are practically identical. The sub-dials retain proper recessed concentric ring definition without looking washed out.
Things get really interesting when you throw ZF into the mix. In the three-way shot below, the genuine sits in the center, M+ is on the left, and ZF is on the right. You can immediately spot how ZF missed the mark on color temperature—their blue leans noticeably darker and muddy.
Zooming in closer on the gen and ZF pair, that color gap becomes impossible to unsee. ZF’s shade lacks the vibrant pastel hue that makes the original piece stand out on the wrist.
Date Wheel Alignment and Font Printing Quality
The date window at 6 o’clock on the Black Bay Chrono is tiny, meaning any misalignment or sloppy printing jumps right out at you. A common issue with budget chronographs is numbers sitting too close to the top or bottom edges of the date wheel cutout.
