Bremont Terra Nova 42.5 ChronographvsCIGA Design BLUE PLANET II

The Bremont Terra Nova 42.5 Chronograph is noted for its 42.5mm Cupro-Aluminium case, which is described as blocky with satin finishing and minimal polishing, and a bi-directional bronze compass bezel with a black ceramic insert. Owners and reviewers highlight the satisfying winding action of the crown and crisp chronograph pushers, though one reviewer found the start/stop pusher required significant force. The watch features a green gradient dial with full-block Super-LumiNova numerals and is powered by a chronometer-rated automatic movement with a 56-hour power reserve and 100-meter water resistance. The CuAl7Si2 bronze alloy case is expected to patina over time, offering a warmer look and increased scratch resistance. One reviewer noted the prototype's rear sapphire caseback was too dark to appreciate the movement, and conspicuous text around the tourbillon window detracted from the dial.

Owners and reviewers widely praise the CIGA Design BLUE PLANET II for its unique, detailed Earth dial design, which is considered well-executed for its price point and frequently garners compliments and sparks conversations. The watch is noted for its comfort, particularly with the soft rubber strap, and its titanium variant is praised for lightness. The dial's three-dimensional Earth map, created with a CNC process for exaggerated topography, is a significant aesthetic feature, with some models including micro-engraved details. The watch utilizes a Miyota 8000-series movement, with one source stating a stated accuracy of -15/+30 seconds per day, while another mentions a Swiss-made CD-04-E automatic movement with a 40-hour power reserve. However, legibility remains a consistent challenge for the CIGA Design BLUE PLANET II, with owners finding it difficult to read the time despite dial improvements and larger, luminescent indices on the hour and minute rings.
