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.
