The most useful thing to know when buying a milestone birthday present is not the person's hobbies. It is which decade they are turning, because the same gift lands completely differently at thirty and at sixty.
This is what actually changes at each one, and what to do about it.
Thirty: marking a transition
At thirty most people are in the middle of becoming somebody slightly different: the job has become a career, the flat may have become a house, several friends have children.
The gifts that land mark that transition rather than resisting it. The good version of something he has owned a cheap version of for a decade. The first properly grown-up example of a thing he cares about.
The other thing that works, and it is the strongest option at this specific age, is anything about the friendship group. Thirty is when everyone starts becoming harder to get in the same room, and it is the last moment when the group from twenty is still fully intact. A gift that captures it is worth far more at thirty-five than it seems at thirty.
Jokes about being over the hill are still fine here. This is close to the last decade where they are.

Forty: stop making it about age
Something shifts at forty and it is worth taking seriously.
Age stops being an abstraction. People at forty are often in the hardest years they will have: young children, aged parents, a career that is either demanding or disappointing, and very little time that belongs to them.
Which means the traditional fortieth gift, a joke about decline, lands differently than it used to. Everyone laughs. Nobody enjoys it.
What works at forty is time and permission. Something that gets him out of the house for a day without needing to negotiate for it. Something entirely for him rather than for the household. An experience with somebody he no longer sees enough of.
The most valuable currency at forty is a day off, and the most useful gift is the one somebody else has organised so he does not have to.

Fifty: people, not things
By fifty most men have acquired all the objects they intend to acquire, and the ones they want next they are entirely capable of buying.
What is genuinely scarce by fifty is people in a room. Friends have moved, families have grown in different directions, and the effort required to assemble the group has become substantial enough that it mostly does not happen.
So the gift is usually the assembling. Getting the right fifteen people somewhere, which is work and reads as a present because it is one.
Alongside it, this is the decade where the personal and specific starts to beat the expensive and generic. Something built around his actual life, rather than an upgraded object, begins to land harder here than it did at forty.

Sixty: their own history
Sixty is where nostalgia stops being a marketing category and becomes genuinely valuable.
At sixty a man's formative years are far enough away to be a distinct era, with its own objects and its own texture, and close enough that he remembers it in detail. Anything that reaches back into it is doing something no purchasable object can.
This is also the decade where the gift can be about him without being about his age, because there is now enough life to draw on. The town. The first car. The band. The machine in the bedroom.
For anyone who was a teenager or a young adult when home computers arrived, this is why a game about that particular moment works so well as a sixtieth present, and it is the subject of 60th birthday gift ideas.
The rules that hold at every decade
Specific beats expensive. A cheap thing that proves you were paying attention beats an expensive thing that proves you were not.
Never make the number the theme. Cards can. Presents should not.
Ask his closest friend, not him. Men asked directly what they want say "nothing" and mean "I do not want to make this awkward".
And anything involving people he does not see enough of will outperform anything you can buy.
