The introduction at Baselworld 2019 of a 43mm, slate-grey version of Tudor's Black Bay Bronze (HK$28,500) diver is further proof (if, indeed, any were needed) that Rolex's entry brand just can't put a foot wrong. Strap it on -- if you can get one, that is -- with either black nubuck or grey fabric.

If the HK$387,000 pricetag of the A. Lange & Söhne 25th-anniversary Lange 1 Timezone in white gold doesn't set your head spinning, here's a view your wrist hairs get of its L031.1 calibre. But from whichever angle you look at it, it's a masterpiece.

If you love classic timepieces and motorsport -- and there can't be many collectors who don't feel the frisson generated by that combination -- then we guess you'll be feeling an itch in your wallet following TAG Heuer's unveiling of a 50th-anniversary limited edition of its Monaco (HK$52,700) at the principality's recent grand prix. Even better, you won't find "TAG" inscribed anywhere on the dial of this eye-catching racing chrono.

Marking the French-Swiss watch brand's ongoing collaboration with the Renault F1 team, Bell & Ross's new BR 03-94 R.S. 19 chronograph is designed to resemble the colour-coded steering wheel of this year's racing car. With carbon-fibre dial and bi-directional rotating bezel, the watch features Renault's signature yellow and black colours and, at HK$49,900 a pop, is limited to 999 pieces.

In a 42.5mm steel case with bi-directional bezel and ceramic insert, Blancpain's reissued Air Command flyback chronograph -- in a limited edition of 500 (at HK$153,500) -- would be your classic pilot's watch, were it not an automatic calibre that beats at 36,000vph, with a red-gold, propeller-shape rotor that's visible through the case back.

Inspired by the colours of the Mediterranean and Chopard's lengthy partnership with the Cannes International Film Festival, the L.U.C XPS Azur, limited to just 10 pieces at HK$295,000 each, features a 40mm case in ethical white gold, a COSC-certified calibre and a hand-guilloché dial in vivid blue.

Among the 2019 additions to Breguet's Grand Complications line is the Classique Tourbillon Extra-Plat Squelette 5395, an exquisitely complex men's timepiece that emphasises craftsmanship as much as its bold technical attributes, and features a skeletonised rose-gold 581SQ calibre with a platinum oscillating weight. You won't, however, get much change from HK$1.8 million.
