Any mum would appreciate a heartfelt card and a generous bouquet of carnations, but we think there’s no better way to thank her for putting up with your dirty diapers and teenage angst than with a lavish diamond-encrusted watch.

Equal part timekeeper and stylish accessory, such watches are beautiful but also functional — more so that the usual pair of diamond earrings or necklace. Behind the clever coverlets of diamonds and other precious gems lie remarkable complications that have been honed to perfection by artisans, making these dazzling pieces of arm candy all the more covetable.

Beyonce’s US$5 million diamond-encrusted watch is adorned with a staggering 1,282 diamonds.

If you want to really go all out, you can take a leaf out of Beyonce’s book and commission a completely diamond-encrusted Hublot Big Bang. Crafted using the expertise of 12 master cutters, five stone setters, and 1,282 diamonds, this one-of-a-kind Big Bang took 14 months to create and costs a whopping US$5 million (S$6.97 million).

Another million-dollar watch that will surely take mum’s breath away is Piaget’s Emperador Temple. As a hidden watch, it doubles up as a bracelet, should she need a (really) fancy accessory for dinner. On it rests 481 brilliant-cut diamonds, 207 baguette-cut diamonds and one emerald-cut sparkler, each lending a bit of sparkle to the overly-opulent timepiece.

Of course, not all of us can afford to splash millions on a customised timepiece, so here are 5 other diamond-encrusted watches that are equally fit for royalty — as your mum deserves.
