What you get for under €100 and what you don't
Below €100, quartz drive rules, and that is good news: a quartz movement is more accurate than any mechanical watch in this class and, depending on the module, runs for years on one battery. Manufacturers such as Casio, Timex or Lorus also produce in volumes that mean only a few euros of production cost per watch. That makes constructions possible that withstand more in everyday life than their price tag suggests.
To be honest, the compromises belong here too. You won't find sapphire crystal in this class; acrylic and mineral glass are the norm. Cases are often made of resin or chrome-plated brass rather than solid steel, bracelets are functional rather than luxurious, and the finishing is clean but not fine. Mechanical movements are also entirely absent: of the 23 catalogue models under €100, not a single one has an automatic movement, and the cheapest automatic is the Swatch Sistem51 at a guide price of around €150.
Why these are still good watches becomes clear from looking at the concepts: the G-Shock was designed as a shock-resistant tool and fulfils that purpose without compromise, the F-91W is meant as a featherlight everyday companion and weighs next to nothing accordingly. Neither is a cheap copy of an expensive watch; both are independent designs with a clear mission. If you accept that, you get the best ratio of benefit to price in the entire watch market.

Our recommendations in detail
Four categories structure the field: robust digital and outdoor watches, retro quartz models with cult status, analogue classics for everyday and office, and ladies' watches with smaller cases. Within each group we sort in ascending order by guide price. All technical details come from the data sheets in our catalogue.
Robust Digital and Outdoor Watches
The Casio G-Shock DW-5600E (approx. €70) is the benchmark of the shock-resistant watch: 42.8 millimetre resin case, mineral glass, 200 metres of water resistance and the proven module 3229. It shrugs off treatment that no other watch on this list should be subjected to. The Casio Duro MDV-106 (approx. €79) delivers the analogue counterpart: a genuine dive watch with rotating bezel, stainless steel case at 44.2 millimetres, mineral glass and likewise 200 metres. At this price that is an exception in the entire market, as the guide to the best dive watches shows in comparison.
If you are looking for world time and the look of the eighties, go for the Casio Collection AE-1200WHD (approx. €50), known among collectors as the Casio Royale: 42.1 millimetres, stainless steel bracelet, acrylic glass and 100 metres of water resistance. The more compact Casio Collection W-800H (approx. €40) offers the same everyday usability in a smaller format with 36.8 millimetres, resin strap and likewise 100 metres, designed for ten years of battery life. Both are sensible second watches for sport, building sites or holidays.
Retro Quartz: The Icons Under €50
The Casio F-91W (approx. €25) is the best-selling watch form in the world and, at 35.2 millimetres, 8.5 millimetres thick and with a resin case, a featherlight endurance runner. Acrylic glass and 30 metres of water resistance mark its limits, but as a second watch for travel, sport or festivals it is unbeatable. The Casio Vintage CA-53W (approx. €40) adds the built-in calculator and its reputation as a film icon to the same character, kept compact at 34.4 millimetres.
The Casio Vintage A168WA (approx. €45) looks a little more grown-up, with a chrome-plated case at 36.3 millimetres, stainless steel bracelet and Illuminator backlight. It is the classic for anyone who wants the eighties look with a metallic presence without spending more than a fifty. If you want to delve deeper into this world, the guides to the best Casio watches and the best digital watches offer suitable follow-up reading.
Analogue Classics for Everyday and Office
The Timex Weekender 38 (approx. €60) brings field watch looks, the Indiglo night light and quick-change textile straps in a 38 millimetre chrome-plated brass case. Its bigger brother, the Timex Expedition Scout 40 (approx. €65), grows to 40 millimetres and 50 metres of water resistance and therefore looks more outdoor-ready. Both are uncomplicated companions, whose character the guide to the best field watches classifies in detail.
For office and suit, the Casio Collection MTP-1302PD (approx. €50) offers surprising substance: stainless steel case at 38.5 millimetres, stainless steel bracelet, mineral glass, date display and 50 metres of water resistance. If you prefer to wear leather, the Festina Klassik F20512/3 (approx. €79) is a slim design with 39 millimetres, only 9 millimetres thick and a blue dial. Further alternatives of this kind are collected in the overview of men's watches.
Ladies' Watches Under €100
The Skagen Freja SKW2668 (approx. €99) is the finest design on this list: 26 millimetre diameter, only 6.8 millimetres thick, stainless steel case, leather strap and a reduced two-hand dial with crystal indices. The Lorus Classic RG319XX9 (approx. €65) relies on classic restraint with 30 millimetres, a stainless steel bracelet and a Seiko quartz movement of type PC21.
If you like it digital and playful, go for the Casio Vintage LA670WEA (approx. €45): a small 24.6 millimetre stainless steel case, Milanese bracelet and pure seventies charm in a watch that sits on any slim wrist. It gets sturdier with the Casio Baby-G BGD-565 (approx. €89), which carries the G-Shock principle on in a smaller format with 37.9 millimetres, mineral glass and 100 metres of water resistance. More models of this kind are shown in the ladies' watches category.
More Models Under €100
The catalogue lists a total of 23 models below the €100 mark, and some of them are good alternatives to our recommendations. The Casio Collection MQ-24 (approx. €27) is the most minimalist analogue watch in the range, the Swatch Once Again (approx. €60) brings Swiss manufacturing, a day-date dial and a case made of bio-based plastic. The Casio Vintage A700WE (approx. €50) is extremely flat at only 6 millimetres thick, and the Festina Mademoiselle F20583/1 (approx. €89) rounds out the ladies' selection with a 35.5 millimetre model with a stainless steel bracelet.
What to Look for When Buying
Glass: Acrylic or Mineral
Acrylic glass is standard on digital watches in this price range and has an underrated advantage: it doesn't shatter and can be restored with polishing paste when scratched. Mineral glass, as worn by the G-Shock DW-5600E, the Casio Duro MDV-106 or the Skagen Freja, is significantly more scratch-resistant, but is more likely to crack under hard impacts. Sapphire glass remains reserved for more expensive classes; our watch knowledge section explains the differences concisely.
Reading water resistance correctly
The figures in metres are laboratory pressure ratings and not diving depths. 30 metres, as on the F-91W or the Timex Weekender 38, means splashes and rain, nothing more. From 100 metres, for example on the Collection AE-1200WHD or the Baby-G BGD-565, swimming is unproblematic, and the 200 metres of the DW-5600E and Duro MDV-106 also cover snorkelling.
Size and weight
The range in this list runs from 24.6 to 44.2 millimetres, which is a world of difference on the wrist. Digital resin models wear smaller than expected because of their low weight, while a 44-millimetre steel case like the Duro's overwhelms slim wrists. Measure beforehand using the instructions in the watch size guide, which saves returns.
Typical mistakes when buying a watch under 100 euros
- Reaching for no-name products: Unknown brands promise an automatic movement and sapphire crystal for 30 euros at the same time. Realistically, neither is possible in this class, and there are no spare parts later.
- Mistaking 30 metres for swim-ready: This rating means splash resistance. If you want to wear the watch in the swimming pool, you need at least 100 metres, as offered by several Casio models in this list.
- Insisting on mechanical: There is no serious automatic watch under 100 euros. If you want a mechanical watch, it is better to plan for the larger budget in the guide to the best watches under 200 euros.
- Underestimating the strap: A fabric or resin strap costs a few euros and completely changes the character of the watch. This swap is especially worthwhile with Timex and Casio.
- Buying for looks instead of purpose: A flat dress watch will not last a year in everyday life on a building site. First think about where the watch will be worn, then choose the type.
As a rule, established models with a long production history beat any trend product. Casio, Timex, Lorus, Festina and Swatch supply spare parts and straps for years. You can find all models filtered under all watches, and you can put two favourites side by side in the watch comparison.
Care: how to make a cheap watch last
Even a 25-euro watch rewards a minimum of care with years of additional running time. The most important point is the battery change: if a watchmaker does it, they check the seals and refit the case back correctly. For models with 100 or 200 metres in particular, this decides whether the water resistance is preserved or the display fogs up.
Acrylic crystals like those on the F-91W, the A168WA or the CA-53W pick up scratches faster than mineral glass, but can be made clear again with plastic polish. Stainless steel bracelets get an occasional wipe with warm water and a soft brush, and fabric straps go into the laundry bag. Leather straps like those on the Skagen Freja and Festina Klassik, on the other hand, do not like moisture and last longer if a fabric strap steps in during summer.
Resin ages under constant UV exposure, which is why watches of this construction should not lie on a windowsill for months. Otherwise, quartz watches are pleasantly undemanding: no servicing, no rate deviation to worry about. Why this is a real everyday advantage over mechanical watches is explained in the guide Automatic vs. Quartz.
Conclusion: the best watch under 100 euros for you
For tough everyday use, there is no way around the G-Shock DW-5600E; for water and a bezel, the Casio Duro MDV-106. If you are looking for an honest second watch, buy the F-91W and you will not miss anything for years. In the office, the MTP-1302PD and Festina Klassik F20512/3 cut a grown-up figure, and on a slim wrist the Skagen Freja, Lorus Classic and Casio Vintage LA670WEA convince with very different characters.
What unites this price class is the absence of a prestige premium: you pay for function, not for a name on the dial. If you are still undecided between type, size and drive, the watch finder gets you to a well-founded recommendation in a few questions. If your budget grows later, these watches remain valuable as uncomplicated second watches.
