Hublot Big Bang 421.NX.1170.RX.1704 White Dial 44mm

The matte white dial is the most useful feature of this configuration. In daylight, it keeps the centre open and readable while the diamonds reflect around it. Under warm indoor light, the white shifts slightly toward cream and softens the contrast with the silver-grey titanium. Product photographs often make the stones look dominant, but on the wrist the dial usually becomes the visual anchor because it stays visually stable while the diamonds flash as the hand moves.

This is also easier to read than many dark skeleton Big Bang models. The hands, numerals and subdial markings stand out clearly against the pale surface, although the chronograph layout remains busier than a conventional solid dial. Buyers who enjoy the Unico architecture but find black open-worked dials too dense may prefer this reference for that reason. Hublot officially describes the display as a matte white dial, while the related 421.NX.1170.RX.1104 uses a matte black skeleton dial.

How Large Does 44mm Feel?

The 44 mm case wears larger than a simple round watch of the same diameter. Crown guards, rectangular pushers and layered side construction create additional width, while the pavé setting makes the outer case appear broader because every surface catches light. It suits medium and larger wrists best, particularly for owners already comfortable with 42–45 mm sports watches. On a smaller wrist, the strap may still secure the watch, but the case will dominate visually.

Titanium improves comfort considerably. The watch looks substantial without carrying the dense weight of an equivalent gold case. Its structured rubber strap bends quickly from the lugs and keeps the head centred during longer wear. It remains too thick and broad for close shirt cuffs, so it works better with open sleeves, casual tailoring, knitwear or short sleeves. Hublot uses satin-finished and polished titanium throughout the case and a lined black structured rubber strap.

What Full Pavé Changes?

This is not simply a standard titanium Big Bang with a diamond bezel. Hublot sets 162 diamonds, approximately 1.1 carats, into the case and 126 diamonds, approximately 1.4 carats, into the bezel. The result is a continuous field of light around the dial rather than one sparkling ring. Exposed H-shaped screws and black side components retain the mechanical identity of the Big Bang.

Three ownership points matter

• The setting hides minor surface marks better than plain polished titanium.
• Cleaning around the case and bezel requires more attention.
• The watch remains noticeable even with simple clothing.

The combination suits someone who wants a jewellery-level sports watch without the warmth or weight of precious metal. It is less appropriate for conservative offices, discreet daily wear or situations where the watch needs to disappear.

Daytime and Evening Wear

Despite the pavé construction, the 421.NX.1170.RX.1704 can enter regular rotation. Its anti-reflective sapphire crystal, 100-metre water resistance, lined rubber strap and titanium deployant clasp support normal daily use, travel and warm climates. Those specifications do not make the case carefree; hard impacts and abrasive surfaces still deserve caution.

The white dial makes the watch more adaptable during the day than many dark pavé references. It works naturally with white, grey, navy and black clothing, while the rubber strap keeps the overall character sporty. At night, the diamonds become more prominent and the watch feels more occasion-focused. It can move between daytime and evening settings, but it will never behave like a quiet all-purpose watch.

Who Should Choose This Reference?

The Hublot Big Bang Unico Titanium Pavé 421.NX.1170.RX.1704 suits a buyer who wants maximum diamond coverage, a large 44 mm presence and a lighter case than gold can provide. It also makes sense for someone who prefers a clearer white dial over the black skeleton display of the related 421.NX.1170.RX.1104. The 1704 adds a diamond-set case and changes the dial character, while both retain titanium construction, a black rubber strap and the same Unico movement.

It is not ideal for a small wrist, a minimalist wardrobe or anyone prioritising discretion. Its appeal comes from the contrast between a bright pavé exterior, a readable white centre and titanium’s lower weight. That is why this exact reference exists: it delivers the visual impact of a fully set Big Bang without feeling as heavy or as formal as a comparable precious-metal model.
