What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Glycine Combat Sub Chronograph Sport

Owners widely praise the Glycine Combat Sub Chronograph Sport for its exceptional value as a Swiss automatic diver, highlighting its refined finishing, thin profile at around 10.4-10.8mm, and accurate movements. The watch is noted for its comfortable wearability, with downward-curving lugs on the 42mm case making it wear smaller than its dimensions suggest, and its unique aesthetic is appreciated for avoiding homage designs. Some owners dislike the "COMBAT" text on the dial and find the original strap or bracelet to be lacking, though it is considered a versatile "strap monster." The lume is described as sub-par by one owner, and another noted an inconsistent power reserve. There is a design critique regarding the date window placement, with one owner calling it a significant flaw while another finds it acceptable due to its alignment with the crown.

Seiko Prospex SPEEDTIMER

Owners widely praise the Seiko Prospex SPEEDTIMER's design, with specific mentions of its beautiful ice blue sundial and compact 39mm case size, which some note wears smaller than its specifications due to a short lug-to-lug distance. Reviewers highlight its racing-inspired aesthetic and versatility, with one owner finding the 39mm solar model a sturdy and reliable everyday watch with 100m water resistance. However, some owners question the value proposition, citing the $700 price for a solar quartz model and a thickness of 13mm, while others expressed a preference for automatic movements. On balance, owners and reviewers appreciate the Seiko Prospex SPEEDTIMER's attractive vintage-inspired design and compact wearability, though some debate its value and thickness for a solar quartz chronograph.
