Wrist fit

- Longines Spirit L3.810.4.53.6 –
- Omega Aqua Terra 220.13.41.21.03.003 –
Same rule of thumb as Watch Finder: case diameter of about 23.5% of your wrist circumference (−2 mm to +2.5 mm), and lug-to-lug no longer than about 29% of it plus 1 mm. A guide, not a rule; flat or round wrists differ.

The Longines Spirit L3.810.4.53.6 has 21 mm lugs. The Omega Aqua Terra 220.13.41.21.03.003 has 20 mm lugs. A strap bought for one won't fit the other. Size charts: Longines lug width chart · Omega lug width chart.
