The short answer

The closest alternative to the Isotope Old Radium is the Tissot Heritage 1938 ($925) — looks nearly identical and Automatic. If price is the constraint, the Glycine Men's Combat Field 40mm Automatic Watch GL0576 at $675 (vs $1,370 for the Old Radium) covers most of the same brief. From the independents, the TSAO Baltimore Founders Edition Cream is the standout microbrand take — looks nearly identical and Automatic. Stepping up, the Vacheron Constantin Fiftysix Self Winding 40mm Pink Gold Watch ($29,200) is where the same idea goes with a bigger budget.
