Jaeger-LeCoultre Master Ultra Thin vs Omega DeVille Prestige 18k Gold Automatic

Both are slim, rose gold dress watches on brown leather with diamond accents, so the choice comes down to movement and finish. The Jaeger-LeCoultre Master Ultra Thin is the more refined watch: a thinner case, sapphire crystal, 50m water resistance and a date, with a 38-hour power reserve from its automatic movement. The Omega De Ville Prestige is the safer, more familiar name and wears well, but its listing gives no water resistance, crystal or power reserve figures, so the JLC is the stronger all-rounder. Buy the JLC for a dress watch you can wear daily; buy the Omega if the De Ville styling and brand appeal matter more to you than specs.

• Choose the Jaeger-LeCoultre Master Ultra Thin if you want a thin rose gold dress watch with a date, sapphire crystal and real water resistance for everyday wear.
• Choose the Omega De Ville Prestige if you prefer its silver dial and classic De Ville look and are happy with a simpler, less specified dress watch.
