## Watch Summary
The Grönefeld 1941 Remontoire Constant Force in 18k rose gold (LE-188) is a refined dress watch with a 39mm polished case, hand-guilloché silver dial featuring small seconds at 6 o'clock and a power reserve indicator at 9 o'clock, housing the manual-wind in-house G4-09 calibre that incorporates a remontoire d'égalité for exceptional rate consistency over its 36-hour power reserve. This independent Dutch masterpiece targets sophisticated collectors and haute horlogerie enthusiasts who value precision engineering and subtle elegance over mainstream bling, with unique highlights including the constant force mechanism, sapphire exhibition caseback showcasing Geneva-striped bridges, and blued cathedral hands for a vintage-inspired aesthetic perfect for black-tie events or boardroom sophistication.
