The Reference

Examined to the movement.

The Hublot Spirit of Big Bang ref. 642.NX.0170.RX brings the brand's tonneau-shaped case architecture to a titanium execution with a transparent, fully skeletonized dial. Introduced in July 2024, this 42mm example pairs a titanium case with a titanium bezel, both secured by the signature exposed H-shaped screws that have defined the Big Bang family since its debut. The openworked dial exposes the automatic movement's bridges and gear train, with applied luminous hour markers and a chronograph layout visible through the sapphire crystal. Power reserve is rated at 50 hours, with the movement built on 31 jewels. The watch is fitted to a black rubber strap with a titanium clasp, consistent with Hublot's fusion of high-tech materials and traditional watchmaking. Pre-owned condition, with box and papers included.

I can't tell you how happy I am with Michael and the team at Palazzo Watches. I've been looking for a specific, very rare AP for a long time. Michael found one and worked with me every step of the way to get it into my hands. He was incredibly professional and accommodated every request and need I had. 10/10, will definitely be back for more.

Fantastic experience from start to finish! Offer honest opinions and recommendations because they truly want you to find the right watch, not just make a sale. The office has an amazing view! Highly recommend for anyone looking for a watch and a first-class experience.

I found my go to place to purchase luxury watches!! Mak and Michael were very professional, transparent, helpful, genuine and kind to me. They made the process of buying my first Rolex very easy. All their watches are authenticated with paperwork and box provided. Mak and Michael were very knowledgeable about each watch and answered all my questions to the fullest extent. I would 100% recommend anybody who is looking for their first or next piece in their collection to come here and purchase a watch.
