Rainbow Edition Black £425
Frosted black 316L case · 54-stone rainbow bezel · Blue stardust dial · 42mm · Batch 5
The Rainbow Edition Black doesn’t ask for a second look. It gets it on the first one. A matte frosted black case carrying 54 mixed rainbow gemstones set into the bezel, with a blue stardust dial underneath. The design is a committed idea executed without hedging: dark case, maximum colour contrast at the bezel, depth in the centre. It’s the most requested watch Tomell London has ever made and it’s released in batches rather than open stock for a reason.
This is your watch if: You want the piece people ask about across the room. If you wear a watch as the thing that makes an outfit complete rather than the thing that disappears into it. If you’ve looked at every other watch in the range and this is the one you keep coming back to.
Not for you if: You rotate watches often and want something that disappears when needed. The Rainbow Edition Black doesn’t disappear.
Pre-order Rainbow Edition Black £425
Diamo Frosted Silver £310
Frosted silver 316L case · Silver stardust dial · No bezel embellishment · 42mm
The Diamo Frosted Silver is the most deceptive watch in the Tomell range. It looks minimal at a distance. Up close it’s not the frosted case texture catches light differently at every angle, and the silver stardust dial shifts between bright and deep depending on where you’re standing. It’s a watch that reveals itself to the person wearing it and to anyone close enough to see it properly. The restraint is the point.
This is your watch if: You appreciate detail that doesn’t announce itself. If you want a watch that holds up under close inspection rather than stopping people across a room. If your style runs toward quality you can feel more than display.
Not for you if: You want immediate impact. The Diamo earns its reaction over time it doesn’t demand one upfront.

Green Rubin Motorsport £310
Gold 316L case · Green dial · Tachymeter bezel · Three-register chronograph · 42mm
The Green Rubin Motorsport is the most technically complex watch in this comparison and the most specific. A full three-register chronograph three sub-dials, tachymeter bezel, stopwatch function in a gold case with a deep green dial. The design references aviation and motorsport instrumentation rather than fashion or jewellery. It’s a tool watch that happens to look extraordinary.
This is your watch if: You want a watch with mechanical purpose something that looks like it does something, because it does. If green dial watches have caught your eye and you want one with more going on than a clean three-hand format. If you wear watches that start conversations about what they are rather than just how they look.
Not for you if: You prefer a clean dial. The chronograph layout is the whole point of the Green Rubin if you want the gold-and-green combination without the sub-dials, the Gilded Oasis is the right call.
