There are numbers that say much more than just the time. Numbers that are not limited to marking the hours, but become symbols of achievements, thresholds crossed, stories to remember. They can indicate an important anniversary in the life of a fashion house, such as a centenary that celebrates the past while looking to the future. Or they can mark the technical achievement of a timepiece capable of withstanding abyssal pressures, pushing itself where no watch has ever gone before. Numbers that speak of passion, research and innovation. That mark the difference between what has been done and what can still be imagined. Because in the world of diving watches, every number counts. It has the power to convey a vision. The vision, for example, that drove Alessia Zecchini, the cover star of Sea Time, to achieve her 40th career record in the year that also marks the 60th anniversary of the launch of Seiko’s first diving watch, for which the freediver is an ambassador.

Yes, anniversaries. For the watch industry, they are not just a point of arrival. They symbolise the stages of a journey that began a long time ago. Like the journey undertaken by Bulova, whose history began 150 years ago and is now being celebrated with a commemorative edition of the MIL-SHIPS, a timepiece that brings to light a glorious page in the history of the American watchmaker. And, staying on theme, never before has the sea been the stage for such special anniversaries as in 2025. Like the one featuring Citizen’s Promaster Aqualand. Hands up anyone who hasn’t worn this timepiece since 1985, which revolutionised diving thanks to its depth sensor. And speaking of depth, 2025 welcomes Tudor to the exclusive club of the thousand. The new Pelagos Ultra is the first timepiece in the Swiss brand’s history developed to withstand depths of up to 1,000 metres below the sea surface. The sea rhymes with summer and, of course, with a range of offerings from Hublot to Mido, Hamilton to Nomos Glashütte, Panerai to Oris, allowing you to enjoy every second of it.
