Nivada Grenchen Antarctic 38mm Automatic

Nivada Grenchen Antarctic 38mm Automatic owners widely praise its excellent quality for the price, with reviewers highlighting its authentic tropical dial recreation and attractive 38mm case proportions. Owners report accuracy ranging from +6 to +9 seconds per day, and one reviewer notes the Soprod P024 movement has a 38-hour power reserve.
