Since the birth of the first Submariner Ref.6204 in 1953, the calendar-free design has long been the standard design of the Submariner. It was not until 1969 that the calendar function was first introduced in Ref.1680. To emphasize its importance, Ref.1680 uses the "small window convex lens" derived from the log type, which can read information more clearly visually. The mirror of the early Submariner was made of acrylic, and the small window convex lens and the mirror were integrally formed. This work laid the foundation for the design of the Submariner thereafter and had a far-reaching influence.
Time came to 1998, and the Ref.14060 that came out that year returned to the calendar-free dial of the first generation product, and was equipped with a 904L case and sapphire crystal. After many years, the "calendar-free ghost" announced its comeback. The Ref.14060M (Cal.3130 movement modification), Ref.114060 (ceramic bezel), and Ref.124060 (Cal.3230 movement) launched thereafter all continued the calendar-free design. The Submariner series features two product lines, "with calendar" and "without calendar", to satisfy the preferences of players who pursue "pragmatism" and "classic tradition".
Unlike the Rolex Submariner, the Omega Seamaster 300M series has incorporated a calendar function since its birth. The first generation Seamaster 300M diving watch, launched in 1993, offers two sizes of cases, 36.5mm or 41mm. There is a helium exhaust valve at 10 o'clock on the side of the case, equipped with an anodized aluminum outer ring and sapphire crystal. The calendar window is located at 3 o'clock in the dial decorated with wavy patterns. The early Omega Seamaster 300M only provided quartz movements, and then added automatic winding movement models.

In 2010, the fifth generation Submariner introduced the Cerachrom ceramic outer ring. The same is true for the Ref.114060 without calendar, which combines a ceramic outer ring with a sapphire crystal to provide a more durable and wear-resistant user experience. In 2020, the diameter of the Submariner series has been slightly expanded from 40mm to 41mm, and the 32 series movement with a 70-hour power reserve has been upgraded. However, compared with the rich color matching of the Submariner calendar type, the color of the calendarless ghost is much more monotonous. Currently, it is only available in a black outer ring, which is more like a tribute to historical works. The early Omega Seamaster 300m diving watch used an anodized aluminum bezel until it was upgraded to a ceramic outer ring in 2018. Or in order to better present the retro texture, the new Seamaster 300m calendarless model returns to the classic aluminum ring. Nowadays, whenever aluminum rings are mentioned, many players are always worried about their durability. In fact, as a material that has been used for diving watches for many years, the reliability of aluminum rings has been tested by time. Its lightness and the characteristics of not being easy to break under external impact are exactly what ceramic rings are difficult to have.
124060 is equipped with Rolex Cal.3230 movement and has a 70-hour power reserve. This is the most widely used basic automatic movement in Rolex. The escapement is made of nickel-phosphorus alloy, which is not affected by high-intensity magnetic fields. At the same time, the blue niobium Parachrom hairspring can withstand certain temperature changes and is equipped with the Paraflex shock-absorbing device designed and patented by Rolex. Since 2015, Rolex has gradually enabled the "Superlative Chronometer Certification" for new products.
