Key Points from the Discussion

• The Singapore service center is noted for its quick service time, impressing collectors who typically send their watches to other locations like London.
• The author services his watches every 5 to 7 years, or around 5 years for watches with more wrist time, aligning with manufacturer recommendations.
• A common misconception is that watch maintenance should mirror car servicing; however, watches do not necessarily need constant servicing if not broken.
• The Patek Philippe Ref. 3940, while no longer in the current catalog, uses the Caliber 240Q, which is still in production and easily serviceable.
• The Ref. 3940 is a highly regarded model, even seen on the wrist of Philippe Stern, placing its owners in esteemed company.
