How big is this Big Bang?

Hublot lists the 301 case at 44mm; the Amazon title says 45mm. It is a large, heavy gold watch either way.

What does 301.PX.130.RX.174 mean?

Hublot’s reference code: 301 is the 44mm Big Bang chronograph, PX the rose gold case, 130 the black dial, RX the rubber strap, and 174 the pavé-diamond setting.

Does a diamond Hublot hold its value?

No; diamond-set Hublots resell well below retail. Buy it to wear it. Nothing here is investment advice.

The watch that made Hublot

Jean-Claude Biver launched the Big Bang in 2005 and it turned a small brand known for a gold case on a rubber strap into the loudest name in Swiss watches within three years. The recipe was fusion: a gold or ceramic case, a rubber strap, six exposed H-screws on the bezel, and a chronograph inside.

This reference takes that recipe to its end: the case and bezel in Hublot’s 18k rose gold, set with diamonds over the bezel and the case flanks. The HUB4100 is an automatic chronograph built on a Swiss base with Hublot’s own rotor and finishing, with about 42 hours of reserve.

What the listing gets wrong

The Amazon table says quartz. It is not; the 301.PX.130.RX is an automatic chronograph, and the sapphire back shows the rotor. The title says 45mm; Hublot lists the 301 case at 44mm. The reference number in the title and the photograph are the guide, and the diamonds are the point.

Every figure here comes from the Amazon spec table where it is right and from Hublot’s published specification for the reference, not from handling the watch.

Buying it new on Amazon

This unit is listed new by an independent dealer through Amazon, with Amazon’s 30-day return window on top of the dealer’s warranty; read the warranty line on the listing, because Hublot’s own warranty runs from an authorised sale.

Diamond-set Hublots resell well below their retail price on the secondary market, which is why dealer stock like this sits on Amazon under boutique retail. This one is bought to be seen. Nothing here is investment advice.
