Spinnaker Spence 300vsNivada Grenchen Super Antarctic 38mm Automatic

The Spinnaker Spence 300 is widely praised for its slim 10.9mm case and 40mm diameter, offering a comfortable and uncommon thin diver design at its price point. Reviewers and owners highlight its value, especially below $350, and its blend of retro design with modern specifications, including a 300m depth rating and a fully indexed bezel. Some owners, however, find the dial printing and bracelet finishing to be less refined, with one noting the bracelet's male end links as a drawback. The consensus is that the Spinnaker Spence 300 is highly regarded for its exceptional value and wearable dimensions, making it a strong contender for an everyday sports watch.

Owners widely praise the Nivada Grenchen Super Antarctic 38mm Automatic's attractive 38mm case proportions and impressive build quality for its $750 price. One owner notes it performs extremely well and shows normal desk diving marks on the clasp. Accuracy figures range from +6 to +9 seconds per day. The Soprod P024 movement has a 38-hour power reserve, and one reviewer found the included rally strap mismatched. Overall, owners rate the Nivada Grenchen Super Antarctic 38mm Automatic highly for its case proportions and build quality at the price.
