What people say

Owners + reviewers, side by side

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

Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic

Owners widely praise the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic as a tough, underrated tool watch with lifestyle appeal, highlighting its robust build and tritium lume for excellent legibility. However, its 46mm size is a common criticism, with some finding it heavy and top-heavy, and the OEM rubber strap stiff. One owner noted the watch runs about 10 seconds fast after three days, and the ETA 2836-2 movement offers approximately two days of power reserve. On balance, owners and reviewers rate the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic highly for its robust tool-watch build and legibility, despite its substantial size.

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.
