Seiko Chronograph Owner Review : Pure, elegant and endearing

The Seiko Crown Chronograph reference 45899 is a unique timepiece, both understated in its design and profoundly significant in its place within Japanese watchmaking history. Dating from July 1964, it marks a pivotal moment for Seiko, and indeed for the global watch industry, coinciding with the Tokyo Olympic Games. Owning and wearing this watch today is like carrying a piece of that era on your wrist. Powered by the Seiko 5719 mechanical caliber, this Crown Chronograph showcases the brand's technical expertise in the early 1960s. At a time when Seiko was striving to establish itself as a credible competitor to Swiss manufacturers, the development of mechanical chronograph movements was a crucial undertaking. The 5719 caliber perfectly embodies this ambition: simple, robust, reliable, and above all, ingenious. Here, there is no complex chronograph with multiple counters, but rather a single-pusher system of exceptional functional purity. A single press starts the 60-second timer, a second press stops it, and the mechanism then resets automatically. This minimalist, almost pedagogical approach was designed for direct and intuitive use, particularly in the context of sporting competitions of the time. This deliberate simplicity is also reflected in the original white dial, perfectly legible and balanced by two central hands. The overall design exudes Japanese precision: nothing superfluous, everything serves the function. The stainless steel case, generously sized for its era (45 x 37 mm and 12 mm thick), offers a strong presence on the wrist without ever being excessive. The case back is undoubtedly one of the most poignant details of this watch: the Olympic flame is engraved on it, along with the date of manufacture, July 1964. This powerful historical marker definitively anchors this piece in the context of the Tokyo Olympic Games. The example I own is in very good overall condition. The strap was replaced with a new, non-original model, while the watch itself was serviced, without attempting to alter it. I made the deliberate choice not to polish it. The micro-marks, the traces of time, are an integral part of its identity. They tell its story, its history, and, in my eyes, reinforce its authenticity. It's a philosophy I often apply: preserve history rather than erase it. I bought this watch on a pure impulse. A huge Seiko enthusiast—I've owned over a hundred pieces—I'm constantly on the lookout, with alerts set on sales websites, always eager to discover a model I haven't yet encountered. When I came across this Crown Chronograph 45899, I didn't know it. And yet, it was an instant connection. An immediate purchase, without hesitation. And looking back, no regrets: it has become one of the centerpieces of my collection. The modern reissues offered by Seiko pay homage to this model, but owning the original from 1964 is a completely different experience. Wearing this Crown Chronograph today means wearing a rare watch, imbued with meaning, and proudly embodying Seiko's watchmaking heritage. It's a watch I deeply appreciate, one I treasure, and one I wear with genuine pleasure, aware of how fortunate I am to own it. A sincere, historic, and endearing piece that perfectly encapsulates what I love about vintage Japanese watchmaking.
