Buying birthday presents gets harder as people get older. By 40, most men have already accumulated most of the things they actually need, along with a sizeable collection of things they don't. This makes another novelty mug or hastily purchased bottle of booze difficult to get excited about.

A milestone birthday deserves something better. That doesn't necessarily mean spending a fortune, but it does mean putting some thought into it. The best 40th birthday gifts tend to be things that will stick around: a better version of something he already owns, a small luxury he'd never quite justify buying himself, or an object that could still be in use when the next big birthday rolls around.

With that in mind, we've put together a list of 40th birthday gifts for men that are actually worth owning. No "I'm not 40, I'm 18 with 22 years' experience" T-shirts required.

A proper watch

There's a reason automatic watches are such popular milestone gifts. They're useful, personal and, unlike most things we buy, a good one can comfortably outlive its owner. That doesn't mean you need to start investigating the current market value of a kidney either. There are excellent mechanical watches available at almost every sensible price point.

The important thing is to find something he'll actually wear. For most men, that means a relatively simple design on a leather strap or steel bracelet rather than an enormous wrist-mounted contraption with more dials than a commercial airliner.

A weekend bag for life

There comes a point when turning up for a weekend away with an overstuffed backpack starts to feel a little undignified. Forty seems as good a cut-off as any.

A proper weekend bag is an excellent milestone gift because it's useful, luxurious and likely to stick around for years. Go for something in leather, canvas or heavyweight nylon, preferably without too many bells and whistles. The best ones only improve once they've accumulated a few scuffs, stains and stories.

A pair of leather shoes

Most men own plenty of shoes. Far fewer own a pair that could conceivably still be going strong in 20 years.

A 40th birthday is a good excuse to fix that. A well-made pair of loafers, Derbies or boots can be resoled and repaired repeatedly, gradually moulding themselves to the wearer's feet along the way. Stick to classic styles and good leather rather than anything too trend driven. There's little point buying him shoes for life if he doesn't want to wear them after Christmas.

A high-end fragrance

Fragrance hits the sweet spot for birthday gifting. It's luxurious without necessarily being ruinously expensive, gets used regularly and feels considerably more personal than another bottle of single malt.

If you know what he normally wears, use it as a starting point. Alternatively, go slightly off-piste with an independent perfumer or niche fragrance house he might not encounter on the high street. Worst-case scenario, he'll smell more interesting than he did at 39.

A cashmere sweater

Cashmere is exactly the sort of thing that makes a good present because it's difficult to justify buying for yourself. A wool jumper does essentially the same job for considerably less money, but that's hardly the point.

Go for a simple crew neck in a colour he'll actually wear and it should become one of the most useful things in his wardrobe. Navy, grey and camel are difficult to mess up. Fluorescent orange, perhaps less so.

A serious piece of outerwear

A really good coat or jacket can be worn for decades, which makes outerwear particularly well suited to a big birthday. It also gives you plenty of room to pick something that reflects the recipient rather than buying a generic "men's gift".

That might mean a wax jacket for someone who spends his weekends in the countryside, a technical shell for a committed hiker or a great wool overcoat for someone whose idea of the outdoors is the 400 metres between the office and the pub.

A big coffee-table book

Not every 40th birthday present needs to cost hundreds of pounds. A substantial, beautifully produced book on something he's genuinely interested in can feel every bit as special.

Photography, architecture, cars, cycling, watches, art, fashion and travel are all fertile territory. The trick is finding something specific enough to show you've actually thought about it. "He likes cars" is a start. "He's inexplicably obsessed with air-cooled Porsches" is much more useful.

A grown-up wallet

Have a look at his current wallet. If it's swollen to the dimensions of a ham sandwich, held together with fraying stitches and still contains a Blockbuster card, you've found your present.

A good minimalist wallet or cardholder is one of life's small upgrades. It gets used every day, improves with age and doesn't need to cost a fortune. Just resist the temptation to buy anything enormous. Forty is also an excellent time to accept that you don't need to carry every receipt you've received since 2017.

A classic pen

Nobody needs an expensive pen. That's precisely what makes one a good present.

A fountain pen or well-made rollerball turns an entirely ordinary object into something worth keeping. It can sit on a desk for decades, pick up the occasional scratch and potentially become something to hand down. Just don't be surprised if he continues using the free biro from the bank whenever the nice one isn't immediately within reach.

A quality pair of sunglasses

Sunglasses are another everyday object where an upgrade can make a surprisingly big difference. Better lenses, sturdier hinges and a frame that doesn't feel like it'll snap when you look at it too enthusiastically are all worth having.

For a gift, steer away from whatever micro-trend happens to be dominating social media. Classic acetate frames and aviators have survived for decades already, which bodes well for their chances of making it to his 50th.

A good camera

Everyone already has an extremely capable camera in their pocket, but that's part of the reason a dedicated one can make such a good present. Photography becomes more enjoyable when it isn't competing with emails, WhatsApp and the temptation to spend 25 minutes looking at Instagram.

A compact digital camera is the obvious choice, but film and instant cameras can be more fun. The point isn't necessarily better image quality. It's having an object that makes him want to take pictures in the first place.

A record player

Streaming has made listening to almost any song ever recorded absurdly easy. Vinyl makes it unnecessarily complicated again, which is apparently something a lot of us quite enjoy.

For someone who loves music, a record player is a gift that can turn into a hobby. It also solves the problem of what to buy him next year, because there's always another album to add to the collection. Just be aware that what begins with one tasteful turntable can eventually require an alarming amount of shelving.

A design classic for the home

Clothes and gadgets aren't the only things worth upgrading at 40. A well-designed object for the home can make a particularly good milestone present, especially for someone who's difficult to buy for.

It could be a lamp, stool, clock, vase, tray or piece of glassware. Look for something with a bit of history behind it and a design that has already survived several decades of changing tastes. If it looked good in 1965 and still looks good now, chances are it'll cope with another 10 years.

A proper chef's knife

For someone who enjoys cooking, a genuinely good chef's knife is the sort of present that gets used almost every day. Looked after properly, it could comfortably last a lifetime too.

Japanese and European knives offer slightly different approaches, but either can be excellent. The main thing is to buy something appropriate to the person using it rather than the most intimidating blade available. Preparing an onion shouldn't require the equipment of a feudal warlord.

A luxurious dressing gown

At some point, a dressing gown stops being something associated with grandfathers and starts looking like an extremely sensible piece of clothing. Again, 40 feels about right.

Go for something indulgent: heavyweight cotton, brushed wool, linen or even cashmere if the budget stretches that far. It's essentially permission to spend Sunday morning wandering around the house looking like the proprietor of a small but profitable country estate.

A piece of art

Art is inherently personal, which means there is some potential to get this spectacularly wrong. But if you know someone's tastes well enough, a print, photograph or original work can make one of the most memorable gifts on this list.

It doesn't need to be prohibitively expensive either. Limited-edition prints and photography can provide a relatively accessible route in. Better still, find something connected to a place, person or interest that means something to him.

A pair of high-fidelity headphones

Technology generally makes poor milestone-gift material because today's cutting-edge gadget is tomorrow's drawer clutter. A good pair of headphones is one of the exceptions.

Buy well and they can last for years, while improving something he probably does every day anyway. Noise-cancelling wireless headphones are ideal for commuting and travelling; wired over-ear models make more sense for someone who takes his home listening seriously.

Something vintage

A 40th birthday doesn't have to involve something brand new. In fact, something with a few decades under its belt already can feel far more appropriate.

A watch is the obvious route – perhaps a vintage Omega – particularly if you can find one from his birth year, but it could just as easily be furniture, a camera, clothing, a record or an old print. The appeal is that you're giving him something genuinely individual rather than another object pulled from a warehouse shelf.

How to choose a 40th birthday gift for him

The easiest mistake to make with a milestone birthday is assuming the present needs to be enormous or enormously expensive. It doesn't. A £50 book chosen because you know exactly what he's interested in is a better gift than a £500 gadget he never wanted.

Instead, think in terms of upgrades and indulgences. What does he use regularly that's overdue for replacement? What has he mentioned wanting but never bought? What would he enjoy owning but consider slightly too extravagant to purchase for himself?

Those questions should get you somewhere. And if they don't, you can always ask him. It might ruin the surprise, but it'll still be better than buying a personalised pint glass with "Vintage 1986" etched into the side.
