1940s Seeland Sterling Silver Watch Overhauled Mainspring Replaced Vintage

SEELAND manual winding watch, overhauled in 2019 and step adjustment in June 2025.
1940s military style.
Silver solid 7 stones.
The waterproof case is over 70 years old, so high waterproof performance cannot be expected.
Back cover: stainless steel.
Case: 1.22 inches in diameter x 1.47 inches lug to lug x 0.46 inches thick x 0.63 inches lug width.
The windshield glass is dome-shaped, making the dial easy to see with the lens effect.
Leather band: black, custom-made Tochigi leather (images 3, 4, and 8).
The broken mainspring and O-ring have been replaced (7th image).
The step adjustment is also complete and it is running smoothly (8th image).
Since the leg width is 0.63 inches, I couldn't find a ready-made band that I liked, so I ordered Tochigi leather in black. It is 0.12 inches thick.
