How to Measure Your Wrist
Precision is at the heart of TSAR BOMBA — including how your watch fits. To ensure the perfect fit, follow this professional method:
- Use a flexible measuring tape: Wrap it around the wrist just above the wrist bone where the watch will sit.
- Note the circumference: Record the measurement in inches or centimeters. This will guide your case size selection.
-
Consider your preferred fit:
- Snug Fit: Watch sits close to wrist bone. Ideal for active wear.
- Standard Fit: One finger fits comfortably between strap and wrist.
- Loose Fit: Watch moves freely on wrist. Relaxed style.
- Strap type: Leather will conform slightly over time. FKM/Silicone straps maintain their original length.
Use this measurement in conjunction with our Case Size Recommendations for the perfect TSAR BOMBA watch.
