365 Automatic Watches UK Miyota 8215, Square Case & Stardust Dial
Most automatic watches are round. Most stardust dials are on quartz movements. The 365 Automatic Collection by Tomell London does both differently a square case, a Miyota 8215 automatic movement, and a blue stardust dial that shifts with every light condition. Four pieces. Three metal tones. One movement that the independent watch world trusts more than almost any other.
If you’re searching to buy a square automatic watch in the UK, this is the complete guide.
Why the Miyota 8215 Matters
The Miyota 8215 is a Japanese automatic calibre manufactured by Citizen’s movement division. It has a 42-hour power reserve, runs at 21,600 vibrations per hour, and is self-winding from wrist movement. Independent watchmakers around the world choose it specifically because it’s reliable without being expensive to service.
Key Miyota 8215 specs in the 365 Collection:
- Self-winding automatic no battery, no charging
- 42-hour power reserve
- 21,600 vph (6 beats per second)
- Hacking seconds seconds hand stops when crown is pulled for accurate time-setting

Why Square?
The round automatic watch is convention. The square automatic is a deliberate departure. A square case creates architectural lines that sit differently under a cuff, fill the visual space more completely, and photograph with more graphic clarity than a round case at the same diameter. The 365 Automatic Collection applies this format to a properly specified Miyota automatic at an accessible price.
