This replica Seamaster 232324 is a Planet Ocean 600M from the 232-series generation, carrying the 232.32.42.21.01.005 reference number. The 232-series established many of the design codes that later Planet Ocean models built upon, and this particular 42mm steel version represents the core of that generation. Omega developed the 232 references with a focus on achieving 600M water resistance in a case that remained comfortable for daily wear above the waterline.

Case & Movement Specs

• Case diameter: 42mm (232-series standard)
• Case material: stainless steel
• Dial: dark with luminous applied indices
• Bezel: uni-directional rotating, ceramic insert
• Crystal: sapphire with anti-reflective treatment
• Bracelet: steel with diver extension clasp
• Movement: automatic Co-Axial
• Functions: hours, minutes, seconds, date

The 232.32 reference at 42mm was the best-selling size in its generation. The case proportions — moderate lug-to-lug distance, controlled thickness, and curved case back — allowed it to wear comfortably on wrists from roughly 17cm upward. The ceramic bezel insert was already standard at this point, predating some competitors by several years.

Caliber Breakdown

The Co-Axial movement in the 232-series uses the escapement design that distinguishes the brand from traditional Swiss lever movements. Reduced friction at the escapement means less lubricant is needed, which extends service intervals and maintains accuracy over longer periods between servicing. The automatic winding rotor is visible through the sapphire case back, showing the decorated movement bridges and the rotor bearing. For a direct comparison with the next-generation Planet Ocean, check the 210.62 at 44mm to see how the design evolved. Both belong to the Seamaster family and maintain the 600M depth specification.

How It Compares

The 232-series Planet Ocean is often considered the “classic” generation by collectors. The dial layout, hand shapes, and case proportions defined what people picture when they think of a modern Planet Ocean. Later 215-series models refined the finishing and upgraded the movement certification, but the 232 references still hold their own on design alone. The 42mm case is the most versatile size in any Planet Ocean generation, fitting under shirt cuffs while still looking like a proper dive watch on a bare wrist. This replica Seamaster 232324 captures the generation that set the standard for everything that followed in the Planet Ocean line.
