What people say

Owners + reviewers, side by side

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

Sternglas Naos Großdatum

The Sternglas Naos Großdatum is praised for its Bauhaus aesthetic and value, with one owner finding it an affordable alternative to other designs. However, some owners report it feels underwhelming and cheap, with a printed-on face, small font, and toy-like hands, and find the strap to be of poor quality. The watch features a 38mm stainless steel case, an Alabaster dial with beige LumiNova, and a Seiko TMI VJ76 quartz movement rated for -20/+20 seconds per month. On balance, owners and reviewers are divided, with the primary point of contention being the perceived quality and aesthetic execution of the Sternglas Naos Großdatum.

Helgray Skyfighter (Refurbished)

Owners widely praise the Helgray Skyfighter (Refurbished) for its handsome, sporty yet understated design, finding it versatile and good value at its price point. One owner notes the watch is in excellent condition with no marks on the case or crystal, and only minor scuffs on the caseback. However, the brand faces criticism for poor build quality, low-quality movements, and a lack of customer service. On balance, owners find the Helgray Skyfighter (Refurbished) to be a versatile and well-priced quartz chronograph, despite concerns about the brand's overall quality and service.
