The Bremont Supermarine 300M is praised for its comfortable 40mm case, which some owners find wears well even on smaller wrists due to its lug design, outperforming some 40mm watches. One forum contributor notes the 40mm case is relatively compact for a 300m diver and is priced at $1375. A reviewer found the 40mm case comfortable. On balance, owners and reviewers appreciate the Bremont Supermarine 300M's wearable 40mm case size and comfortable wearability.
Owners widely praise the Knot Watches AT1-40SSV for its solid build quality, clean aesthetic, and good finish, with the small seconds hand accurately hitting its markers. The 40mm case size is generally considered good, though one owner felt it wore "a tad on the small side." Opinions on the included straps are divided, with some appreciating their unique Japanese fabrics and leathers and finding them soft and ready-to-wear, while others express disappointment with their quality and note they can be stiff initially. One owner also flagged the small crown as a nitpick due to its low placement. Overall, owners rate the Knot Watches AT1-40SSV highly for its overall quality and finish at the price point.
