Ranking by Thinness: Choosing for Sleeve Clearance
- GW-M5610U / UBC：12.7mm… Among the thinnest, unlikely to interfere with suit cuffs.
- GMW-B5000D / GD：13.0mm… Surprisingly thin even in metal; heavy, but good sleeve clearance.
- GW-5000U：13.2mm, DW-5600UE：13.4mm… Standard thickness for comfortable daily use.
A thickness guideline for fitting under cuffs:
If you want it to fit under a suit or shirt cuff comfortably, use up to approximately 13.5mm as a general benchmark.
The GW-M5610U/UBC and GMW-B5000 meet it.

Size and Compatibility: A Caution
Even when sizes are similar, different bezel or band mounting structures—tabs, button holes, or lug shapes—prevent swapping.
Use this article for wearing comfort and the Compatibility Guide for parts interchangeability.
For example, GW-M5610U and GW-B5600 have similar dimensions, but my hands-on tests showed no bezel compatibility, with gaps or lifting when fitted.
