How to wear it: Take a leaf from the style manuals of the chaps mentioned above and wear yours with relaxed separates and a touch of swagger.

Dress Watches

Omega

Simple, elegant, classic – a dress watch should be all of those things. As the name suggests this is the companion to your suit – dinner or business.

It should be slim enough to slip discreetly under a shirt cuff and subtle enough not to be noticed – this is not the time for chunky chronographs or oversized diving bezels. The quintessential dress watch is time only, though a small seconds’ sub-dial is permitted, maybe a date window if you’re not meeting the queen.

Of all the categories, this is the one where you should spend as much as you can because like a bespoke suit, you should only need one and it should last a lifetime. Think precious metals rather than steel if the budget allows, leather straps are a must here – bracelets look a little gauche – and remember to retire it when you hang up your suit. Scratches are never a good look.

How to wear it: With dressed-up tailoring, of course.

Smart Watches

Tag Heuer

The Big Question: is this a real watch or a wearable computer that just happens to look like a watch? There’s no consensus around an answer but a smart watch invariably has a touch-screen “dial”, connects to your phone, tracks your health and has apps that can guide you around cities, monitor your golf swing, give you recipes for dinner, help you order a takeaway when said dinner goes wrong or translate what the gorgeous woman you just met at a bar in Barcelona said to you.

Generally speaking, there’s Apple’s operating system and everyone else’s designed by Google’s Wear OS operating system, though Samsung also has its own proprietary system for its Galaxy line of watches. There are hybrids that look like watches but have the smart capacity, however, they tends to be limited to heartbeat tracking, sleep monitoring and maybe notification alerts.
