The MB&F Horological Machine No. 9 Sapphire Vision Ref. 91.SYL.GR represents a masterpiece of avant-garde design and technical sophistication. Its 57 x 47mm case, crafted from sapphire and yellow gold, not only exudes luxury but also showcases MB&F's dedication to transparency, allowing an unobstructed view of the mechanical artistry within. The open case back further highlights this intricate movement, framed by the contrast of vibrant green and luminescent accents on the dial, enhancing both visual appeal and legibility.
 

At its heart lies the manual-winding HM9 caliber, a marvel of engineering that boasts a 45-hour power reserve. The movement features two fully independent balance wheels connected by a planetary differential, ensuring both precision and stability. The innovation extends to the watch’s shock-absorbing helicoidal springs, which connect the movement to the case, safeguarding its mechanics. Additionally, the dual spherical turbines under the movement not only serve as a visual spectacle but also contribute to the timepiece’s protection by regulating air pressure and minimizing shocks. Water-resistant to 30 meters, the Sapphire Vision is fitted with a black alligator strap and a secure folding clasp, combining elegance with wearability.

This horological work of art goes beyond simply telling time; it embodies a futuristic vision of watchmaking, where form, function, and artistry are seamlessly intertwined.

Best purchase experience I could have imagined. Donald from Wrist Aficionado was very helpful and responsive whether by text, phone call or email. Shared videos with me and helped me get the watch I have been chasing for sometime. I have found my preferred watch dealer and will be a repeat customer. Payment processed same day and the watch ship later that day. A Very Happy Customer. Thank you everyone at the WA team!

Dealing with Vadim was a pleasure. The price was very fair and the communication and service was perfect. I buy a lot of watches and this experience was as good as they get. The audemars piguet arrived right on time and packaged beautifully. They even threw in a little gift!
