You can’t go wrong, except perhaps with your bank manager, with a diamond-encrusted watch. Our top pick: Blancpain’s Ultra-Slim Mother of Pearl & Diamonds. Trust us, you’ll thank us for it come 14 February.

This elegant watch is classically feminine in its design. Its 18 carat white gold case is subtly embellished with mother-of-pearl marquetry on the dial – an elegant flower-inspired design. And then, of course, there’s the diamonds – both rows of them.

It comes with a white alligator leather strap and a 100-hour power reserve. The latter ensures that the watch will keep perfect time for days, so she’ll never have an excuse to be late again (ahem). And if she asks why you opted for an ultra-slim case, just explain that it matches her figure. See, all bases covered. Phew.

This piece is available at the Blanpain boutique, New Bond Street for £22,160.
