Exactly the same as shown in the video and photos. I knew I made the right choice the moment I opened the box. Excellent craftsmanship!

The case has a great shine, and I snapped this photo 📷 to show my friend—he couldn’t even tell it wasn’t a real Rolex 😂 The dial color is very accurate, and the blue part of the bezel reflects beautifully under different lighting. Gets a lot of compliments when I wear it. Super satisfied

This is my first GMT, and it did not disappoint! 🎯 I compared every detail with the official product photos—fonts, bezel, crystal curve—all nearly identical. 🕰️ Timekeeping is spot on, gaining less than 10 seconds a day, which is amazing. Highly recommended!

This is my third fake Rolex, or I should say replica because it's damn good and truly requires appreciation. The box looks nice but it lacks some weight or sturdiness.. not sure what exactly but I could tell it's not authentic.

This watch strikes the perfect balance between elegance and affordability. The design looks high-end, and the automatic movement adds a premium touch. It’s become my go-to daily piece. That said, the timekeeping could be more consistent — mine tends to gain a few minutes over the week.

I’ve had this black dial GMT-Master II homage for over a month now, and it’s become my go-to daily watch. The design is sleek and minimalist compared to the more colorful Pepsi or Batman versions — which makes it perfect for both work and casual wear. The black ceramic bezel has a subtle shine that catches the light just right, and the dial is deep and rich with perfectly aligned markers. The second time zone feature works as expected, and the independent hand is easy to set. The movement has been consistent, gaining around 8 seconds a day, which is well within what I’d expect from a mechanical. For the price, the build quality and finish are phenomenal. It’s hard to believe it’s not the real thing at a glance.

The moment I opened the box, I was stunned by the depth of the blue dial — it's rich, glossy, and shifts beautifully under different lighting. This watch doesn't just look good, it feels high-end. The brushing on the bracelet and case is clean and smooth, and the polishing around the bezel adds just the right amount of shine.
