Sizing, honestly
Which size fits your wrist?
The question that stops people buying a watch online is "will it fit me?" — so measure first. Wrap a strip of paper around your wrist, mark it, and lay it against a ruler. That number in millimetres answers everything below.
The range, by size
| Model | Case | Thickness | Strap width | Fits wrists |
|---|---|---|---|---|
| Acorn (beech or walnut) | 36 mm | 8 mm | 18 mm | 133–170 mm |
| Favourite (beech or walnut) | 40 mm | 8.5 mm | 20 mm | 160–205 mm |
| The Carbon Portal 40 | 40 mm | 8.5 mm | 20 mm | 160–205 mm |
| Albatross (beech or walnut) | 44 mm | 8.5 mm | 22 mm | 160–205 mm |
| The Carbon Portal 44 | 44 mm | 8.5 mm | 22 mm | 160–205 mm |
The automatics — skeleton and date — come in the same 40 mm and 44 mm case diameters.
Reading your number
- 133–160 mm — the Acorn is the one. The others start at 160 mm and will sit loose or not fasten.
- 160–170 mm — everything fits; it becomes a question of presence. 36 mm is discreet, 44 mm is a statement.
- 170–205 mm — the 40s and 44s. The Acorn won't fasten.
The Acorn is genuinely the small watch of the range — its 133 mm lower bound reaches wrists nothing else here fits. Product photographs are all framed to fill, so every case looks the same size in them; trust the measurements, not the photos.
The weight — or the lack of it
A Bettél watch weighs 26 grams. A steel watch of similar size typically runs 80–150 grams — so this is roughly a fifth of the weight of what you're probably wearing now. If you find watches heavy, or have never worn one comfortably, that number is the reason to try wood.
And the sunglasses
The Curve is a 143 mm frame — a medium. Its page has the lens choices, and a smaller size is coming.
