Can You Wear a Smartwatch in a Football Match?
What IFAB Law 4 actually says about smartwatches and wearable tech in football, why most refs ask you to take it off, and how to wear yours on the pitch without the awkward five-minute chat in the centre circle.

The short answer
Yes — but not on your wrist. IFAB Law 4 permits wearable technology in matches, but a smartwatch on your wrist will get you pulled aside before kick-off. The answer is the Scorza Performance Vest: it holds your Apple Watch or Garmin in a padded pocket on your back, completely covered under your match shirt, so you can track every match without a word from the ref.
What IFAB actually says about wearable tech
The International Football Association Board (IFAB) writes the laws of the game. Every league in the world — from the Premier League down to your local Sunday league — runs on the same rule book.
Law 4, the Players' Equipment law, is the relevant one. The key passage on wearable tech reads, in essence:
"The use of electronic communication and electronic performance and tracking systems (EPTS) is permitted, provided that the equipment is not dangerous and complies with the relevant safety standards."
That is the whole legal basis for wearable tech in football. The single test is: is it dangerous?
So what counts as dangerous?
The law does not list specific products. It leaves the call with the referee, who applies common sense before kick-off. In practice, refs at every level apply the same rough rules:
Hard objects on exposed parts of the body that could injure another player — watches, jewellery, rings — usually have to come off or be properly covered.
Anything that could injure the wearer in a fall or collision — sharp edges, things sticking out — same answer.
Soft, body-conforming, padded equipment — like compression baselayers and GPS vests used by every Premier League club — is fine.
That is why professional players wear GPS vests in every match — soft, tracker flat between the shoulder blades, padded and protected, no damage in a tackle. And why a referee will ask you to take a smartwatch off your wrist. A bare metal watch in a tackle has a real chance of cutting someone.
So can you wear a smartwatch in a match or not?
Three honest answers depending on what you actually want:
1. On your wrist: no
A bare metal watch in a contact sport is a hazard — to you and to anyone you tackle or are tackled by. Referees at every level will ask you to take it off, and most 5-a-side centres now operate a blanket watch-off policy regardless of what you say. Do not count on getting it past the warm-up.
2. On your wrist with a sweatband over it: still no
The sweatband argument does not hold up. The metal case is still hard underneath, and most refs know it. It is not worth the argument before kick-off, and it will not survive an equipment check in a competitive match.
3. In a Scorza Performance Vest: yes, every time
The Scorza vest holds your watch in a padded pocket lower on your back, offset to one side — on the fleshy part of your back, away from the spine. It sits underneath your match shirt — completely covered, nothing visible, nothing for a referee to question. The same Law 4 safety logic that allows professional GPS vests applies here: padded, body-conforming, no exposed metal, no danger.
Why we built the Scorza vest the way we did
When we set out to make smartwatch football tracking actually work, the wrist question was the first thing we had to solve. A watch on your wrist gets you pulled aside before kick-off. A watch tucked into a sock does not track accurately. Neither option actually works.
So we put the watch where it belongs: secured in a padded pocket on your back, held safely against your body, with the vest sitting underneath your match shirt. Completely covered. Nothing visible to the referee, nothing hard or exposed in a tackle, nothing to argue about in the centre circle before kick-off.
The padding cushions the watch from impact. The placement keeps it away from any contact. And because it is under your kit, there is no judgement call for anyone to make — the ref sees a player in a baselayer, same as every other player on the pitch.
What about competitive matches — FA, county leagues, university football?
Same answer. Every affiliated competition in England runs on IFAB's Laws of the Game, and the FA's match-day handbook defers to Law 4 for player equipment. The same applies in most countries. There is no separate "no wearable tech" rule sitting on top — it is purely the dangerous-equipment test, judged by the ref.
If you are playing in a league with a particularly strict equipment check, the safe path is the same: wear the tracker in a vest pocket on your back, under your shirt, and there is nothing for the ref to question.
What if my ref still asks me to take it off?
If you are wearing a Scorza vest under your kit, this almost never happens — there is nothing visible to flag. If for some reason you get pulled up:
Show the ref where the watch is — flat against your back, padded.
Reference Law 4: wearable technology is permitted provided it is not dangerous.
If they still say no, take it off and put it in your kit bag. Do not argue. The ref's call is final on match day.
Frequently Asked Questions
Is wearing a smartwatch in football illegal?
Not under IFAB's Laws of the Game. Wearable tech is explicitly permitted. The catch is the "not dangerous" requirement, which is why most refs ask for watches to come off the wrist.
Why do refs make players take watches off?
A bare metal watch on the wrist is a hard, sharp object in a contact sport. The ref's job is to keep players safe — and the easiest way to do that is to ask you to remove it before kick-off.
Are GPS vests allowed in matches?
Yes — they are worn in every professional football match in the world. They are soft, padded and body-conforming, which means they pass the "not dangerous" test in Law 4 without question.
Can I wear an Apple Watch in a 5-a-side match?
Most 5-a-side centres now ask for watches off as a blanket safety policy. A vest is the workaround that lets you keep tracking without the argument.
Does the Scorza vest count as approved equipment?
There is no central approval scheme for amateur kit — equipment is judged match by match against Law 4. The Scorza vest is designed to satisfy the same safety logic that approves every professional GPS vest in the world.
Wear the watch. Keep the ref happy.
