Best Watches Under £100 UK
The under-£100 watch market in the UK contains genuinely excellent options from Seiko, Casio and Orient — not just compromises. Japanese quartz and automatic movements in this price range offer reliability and value that European equivalents at the same price cannot match. We cross-referenced UK watch community opinions on WatchUSeek, r/Watches and Amazon UK to identify the best timepieces under £100 in the UK.
What to Look For
- 1Japanese movements (Seiko NH35/36, Orient in-house, Miyota) are the most reliable under-£100 options in the UK — avoid unbranded 'Swiss style' movements at this price.
- 2Mineral glass scratches more easily than sapphire — a watch under £100 will likely have mineral crystal. Consider a crystal protector or be prepared for surface scratches.
- 3Casio G-Shock is the practical toughness benchmark at under £100 — shock, water and dust resistance that no dress watch at this price can match.
- 4Seiko 5 automatic (SNKL/SNKE/SNK range) is the UK community's recommended starter automatic under £80 — genuine Seiko movement quality at a low price.
- 5Avoid fashion watches from premium-appearing brands (MVMT, Vincero, Cluse) at £50–£80 — they use generic Miyota movements in overpriced cases.

Honourable Mentions
Editor's Note
The UK watch community is clear that the best under-£100 automatic is the Seiko 5 range, and the best under-£100 quartz is the Casio MTP-V004 or G-Shock GA-2100. Orient Bambino is the best under-£100 dress automatic. These three cover 95% of UK buyer needs at this budget.
Our Take
If you want an automatic watch for under £100 in the UK, the Seiko SNK809 (or the newer Seiko 5 equivalents) is the only recommendation worth making. If you want a quartz dress watch, Casio MTP-V004. If you want something indestructible, Casio G-Shock DW-5600. These are not 'good for the price' — they're simply good watches that happen to be cheap.
