How we made this selection

This isn’t a list of bestsellers: it’s a selection based on technical criteria. We’ve ruled out models with inflated specifications, compared what really makes a difference in day-to-day use, and ranked the options according to what they offer for the price. The affordable range starts at around €100, the sweet spot is around €160, and anything above €280 is only worth it if you’re going to make the most of specific features. Below you’ll find the full criteria so you can judge for yourself.

Straps and bracelets: the most cost-effective change

Changing the strap transforms a watch for €20–40 and is the best value-for-money upgrade there is. Measure the width between antlers (18, 20 and 22 mm are the most common) and choose according to your needs: steel for everyday use, skin for washing (never with water), rubber or FKM for sport and summer, and NATO made of nylon for a military look and quick changes. Look for pins made of quick release (quick-release) so that no tools are required. With steel bracelets, the detail that sets the good ones apart from the mediocre ones is the micro-adjustable fastening, which allows you to fine-tune the fit when your wrist swells in the heat.

Water resistance: what the ATM rating really means

The figure on the box does not represent the actual working depth; it is a static laboratory pressure reading. In practical terms: 3 ATM / 30 m It can withstand rain and splashes, but nothing more; 5 ATM allows you to wash your hands but not to have a shower (the hot water exceeds that pressure and the heat causes the seals to expand); 10 ATM it’s suitable for swimming; and 20 ATM / 200 m That’s the minimum for diving. If you want a proper diving watch, look for the certification ISO 6425, which can be identified by the word printed on the dial DIVER'S alongside depth.

Accuracy: how to tell if your automatic gearbox is working properly

An automatic watch is not a precision timepiece, and you shouldn’t judge it as such. To measure it properly, set it to the same time for seven days in a row treat it as normal and calculate the average daily deviation: within -10 / +30 seconds a day This is within the factory specification for an uncertified calibre. If it falls outside this range, it is almost always corrected by means of a regulation at a watchmaker’s (€30–60), not as part of a repair. A useful tip: the position in which you leave it overnight affects the result, so if it’s running fast, you can leave it face up, and if it’s running slow, with the crown facing upwards.

The gauges that are actually inside

Almost all automatic cars costing less than €500 are fitted with one of these engines: Seiko NH35/4R35 (reliable, hackable, 41-hour power reserve, the standard for affordable watches), Miyota 8215 (cheap, second hand with a slight wobble) or Miyota 9015 (finer and at 28,800 alternations). Moving up, we find the ETA 2824-2 and its equivalent Sellita SW200, and the Powermatic 80 by Tissot, which stands out for its 80-hour power reserve. Knowing the calibre tells you more about the watch than the brand: two watches with very different price tags may share the same movement.

Power reserve – and what happens if you don’t have one

Power reserve is the length of time an automatic watch continues to run after you stop moving it: typically, this is 38–41 hours in traditional calibres, which means that if you take it off on Friday night, it will have stopped by Monday. Modern movements have extended that figure: the Powermatic 80 lasts up to 80 hours and some current calibres at 70. For several automatic watches, a rotary box It keeps them running, although this isn’t essential: leaving it switched off won’t damage the mechanism; it just means you’ll have to set the time again. What is advisable, however, is a service every 5–8 years.

Quartz, automatic or manual: which to choose and why

The quartz It is the most accurate and the most practical: it diverts around ±15 seconds per month, it needs nothing more than a new battery every 2–4 years and is more shock-resistant. The automatic It is powered by a wrist movement and deflects between -10 and +30 seconds a day (a COSC-certified calibre has a rate of between -4 and +6), but it is the one with a mechanical soul, a sliding seconds hand and long-term value. The manual It needs to be wound every day and is usually more delicate, which is why it’s used in dress watches. If you’re looking for accuracy, go for quartz; if you’re looking for fine watchmaking, go for an automatic.

Conclusion: what to buy depending on your situation

If you’re looking for the safest choice, go for the Casio G-Shock GA-2100. If your priority is everyday wear, the Hamilton Khaki Field Mechanical is a better fit. And if budget is the deciding factor, stick with an entry-level model costing around €100 rather than a higher-end model from a lesser-known brand: when it comes to watches, reliability counts for more than the technical specifications. Check the current price before you decide, as it changes frequently.

Frequently Asked Questions

Will an automatic car break down if I leave it standing?

No. Leaving it switched off won’t damage the mechanism; you’ll just need to set the time when you use it again. What it does need over the years is a service, every 5–8 years depending on use.

Can you tell the difference between 316L and 904L steel?

In day-to-day use, not much. 904L offers slightly better corrosion resistance and can be polished to a higher shine, but it is more expensive to machine, which is why few brands use it. Surgical-grade 316L is the industry standard and is more than adequate for everyday use, even when exposed to sweat and salt water.

Leather, steel or rubber strap?

Steel for everyday use and water, because it can withstand anything and cleans itself. Leather for dressing up, bearing in mind that with sweat it will last between one and two years. Rubber for sport and the beach. If the watch has quick-release buckles, having two straps completely transforms the watch in ten seconds and costs less than €25.

What does it mean for a watch to be ISO 6425-compliant?

It has passed the standardised tests for diving watches, not just the pressure test. It can be recognised by the word ‘DIVER’S’ printed on the dial next to the depth marking; without this marking, it is a water-resistant watch but not a certified diver’s watch.

How much does an automatic watch gain or lose per day?

A well-regulated mid-range movement typically runs between -10 and +30 seconds a day; a COSC-certified chronometer runs between -4 and +6. If yours falls outside this range, it can almost always be corrected with a service costing €40–70 at a watchmaker’s, rather than a full repair.

Should I go for the Casio G-Shock GA-2100 or the Hamilton Khaki Field Mechanical?

The Casio G-Shock GA-2100 is the most well-rounded option and our default recommendation. The Hamilton Khaki Field Mechanical is a good choice if your priority is everyday wear. As a guide for your budget, the price range starts at around €100, and the best value is usually found at around €160.
