What people say

Owners + reviewers, side by side

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

Oak & Oscar The Humboldt GMT SAR Edition

Oak & Oscar The Humboldt GMT SAR Edition is praised for its anti-magnetic properties, sandwich lume dial, and overall construction quality for its price point. It features a brushed Grade 5 titanium case, a navy blue sandwich dial with an orange minute track and seconds hand, and a Sellita SW330 movement with a 56-hour power reserve. Minor drawbacks noted include bracelet sizing adjustment and lume brightness. On balance, owners and reviewers rate Oak & Oscar The Humboldt GMT SAR Edition highly for its robust construction and unique dial design at its price point.

Zelos Helmsman 3

Owners widely praise the Zelos Helmsman 3 for its exceptional finishing and polishing on the titanium case, with some noting it feels nicer than previous models. The unique Titanium Crystalline Dial and Damascus Titanium dial are frequently highlighted as aesthetically pleasing and head-turning features, especially considering the price point. The brushed beads of rice bracelet is described as fitting well, and the on-the-fly clasp is considered amazing. Lume is also noted as great, with lumed crowns being a positive observation. However, some owners report the watch can feel top-heavy with sharp edges, making it uncertain as a daily driver for some. The meteorite bezel is seen by one owner as not adding significant value, and the stock strap's keepers and stitching were considered to detract from the watch's appearance.
