Watches for Those Looking to Save Money: 2026 Guide

Start here

This guide is organised from the most important points to the least important. If you’re only going to read two sections, read the first two: that’s where most of the difference lies between making the right choice and regretting it. At the end, you’ll find a glossary of terms that you’ll see repeated in the product descriptions, explained in plain language.

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.

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.

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.

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.

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.

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.

Case size: the important figure is not the diameter

Everyone looks at the diameter in millimetres, but the person who decides whether a watch suits you is the lug to lug, the distance between the lugs. Rule of thumb: for a 16–17 cm wrist, look for a lug-to-lug measurement of just under 48 mm; up to 50–52 mm if your wrist is over 18 cm in diameter, 36–38 mm It is the classic style and the one that works best on a slender wrist or with a suit, 39–41 mm It’s the most versatile size available today, and anything over 44 mm takes you into the sports watch territory. A 40 mm watch with long, curved lugs looks better on the wrist than a 38 mm one with straight lugs.

Glossary: the terms you’ll see in the fact sheets

Lug to lug

The distance between the ends of the lugs. This determines how the watch sits on the wrist.

Power reserve

The number of hours a mechanical watch continues to run without being wound or set in motion.

Hacking

A function that stops the seconds hand when the crown is pulled out, to synchronise to the second.

ISO 6425

A standard certifying a watch as suitable for diving. It is marked ‘DIVER’S’ on the dial.

Alternations

Vibrations per hour of the movement (21,600 or 28,800 are the most common).

Fine-tuning

A clasp system that allows the size of the bracelet to be adjusted in small increments.

Super-LumiNova

Non-radioactive phosphorescent paint that absorbs light and glows in the dark.

Conclusion: the three-step decision-making process

In a nutshell: work out what you’ll actually use it for, narrow it down to the two or three features that really matter to you, and tailor your budget accordingly. With that in mind, the Citizen Eco-Drive BM8180 is the default choice, whilst the Seiko Presage Cocktail is the alternative if your priorities lie elsewhere. Everything else — extra features, promotions, high-end models — is secondary if those three steps are sorted out properly.

Frequently Asked Questions

Do sundials need maintenance?

Virtually none. The cell lasts between 10 and 20 years and the capacitor can be replaced; under normal lighting conditions, even artificial light, they remain charged and retain a reserve of power for months in the dark.

How much does it cost to change a watch battery?

Between €8 and €20 at a watchmaker’s, depending on whether the case needs to be unscrewed and the water resistance retested. With a water-resistant watch, it’s worth paying for the pressure test: changing the battery without replacing the gasket is the most common reason for moisture to get in months later.

What size watch suits me best?

Focus on the lug-to-lug measurement rather than the diameter: under 48 mm for wrists measuring 16–17 cm, up to 52 mm if your wrist is over 18 cm. In terms of diameter, 39–41 mm is the most versatile range, whilst 36–38 mm is the classic choice for a slender wrist or a suit.
