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.

Boldr Rally

Owners widely praise the Boldr Rally's compact 38mm titanium case and excellent value under A$500. The VK64 mecaquartz movement has proven reliable for years, and the sapphire crystal is a welcome feature. Some owners find the dial busy and difficult to read, particularly the black hands against the black subdial, and note the bead-blasted titanium case can be a scratch magnet. The default straps have been described as boring or not holding up to daily wear. Overall, owners rate the Boldr Rally highly for its robust titanium construction and excellent value, despite some legibility concerns.

From video reviewers

The 38mm titanium case with a 44mm lug-to-lug measurement provides a comfortable and compact fit. The 200m water resistance is noted as robust for a chronograph. The 14mm thickness was mentioned as potentially substantial for the watch's size.
