Women’s watches: sizes, materials and choosing by style

From the classic 28 mm to the unisex 36 mm: which size works best, which materials stand up to everyday wear and tear, and which models stand out.

Steel, titanium and coatings

The standard is the 316L steel, surgical grade, corrosion-resistant and easy to polish. The 904L (which Rolex calls Oystersteel) is slightly more corrosion-resistant and produces a denser polish, but the difference in everyday use is minimal. The titanium It weighs 40 per cent less and is hypoallergenic, making it ideal if you find the weight a problem, although it does show wear more easily. Regarding coatings: the PVD It is a thin layer that eventually wears away at the edges, whilst the DLC It is much harder and lasts for years. The gold plating on cheaper watches usually lasts between 2 and 5 years of daily use.

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.

How to buy a watch without being ripped off

Four things to check before paying: that the salesperson whether it is the manufacturer or an authorised distributor (on marketplaces, check who is shipping the item and who is invoicing); that the warranty that it is the brand’s official specification in Spain and not just that of the seller; that the specifications advertised match the official profile from the manufacturer, particularly crystal and ATM models, as these are where claims are most often exaggerated; and ensure the price isn’t significantly below market value, which is a common sign of a replica. Keep the box, paperwork and receipt: with watches, these add to the value should you ever sell it.

Glass: sapphire, mineral or acrylic

The sapphire is hard 9 on the Mohs scale: Only a diamond or materials containing corundum can scratch it, which is why it’s the best choice if you’re using the watch every day. The mineral (hardness 5–6) can be scratched by sand, keys or cement, although it withstands a single impact better without chipping. The Hardlex Seiko’s is a hardened mineral, somewhere in between. The acrylic It gets scratched just by looking at it, but you can polish it at home with polish in two minutes, giving it that warm, domed look of vintage watches. An anti-reflective coating on the inside makes the dial much easier to read than one on the outside, which wears off.

Solar and Eco-Drive: the maintenance-free option

If you don’t want to change the batteries or set the time, solar technology is the most practical solution on the market. The Eco-Drive Citizen charges a cell using any light, including artificial light, and stores energy to 6 months in total darkness; the Seiko equivalent is the Solar, and its Kinetic generates electricity from movement. The Spring Drive The Grand Seiko is a hybrid watch with a perfectly smooth seconds hand and quartz-level accuracy. The solar cell lasts between 10 and 20 years – far longer than the batteries it replaces – and the capacitor is replaceable.

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.

Frequently asked questions about ladies’ watches

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.

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.

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.

Can a smartwatch replace a traditional watch?

For training and receiving notifications, yes. As an object in its own right, no: a smartwatch becomes obsolete in three or four years and its battery only lasts a day, whereas a well-maintained mechanical watch can last well over thirty years. Many people end up owning both and switch between them depending on the day.

What budget do I need for women’s watches?

It depends on how you plan to use it: there are good options in the entry-level range, as well as advanced models that are only worth the extra cost if you’re going to make the most of their features. Check the criteria in this guide, work out how you’ll actually use it, and compare the current price on Amazon before making a decision.
