Omega Speedmaster Automatic Triple Date Ref. 3513.50 — 39 mm — Stainless steel, black dial, automatic chronograph, Pre-owned 1998 — Omega service box — Mostra luxury case — 3-year Mostra warranty

“A watch that offers complete functionality while remaining discreet on the wrist, designed to follow every day without ever overdoing it.”

In the morning, you put it on as you might choose a good fountain pen for the day: a working instrument, but with real character. The black dial structures the information without overloading it, the sub-dials are organised around the central axis, and the chronograph hand waits for its cue. A single glance is enough to pick out the date, day and month – practical for busy schedules, meetings and travel. At the office it slips under a shirt cuff and sits easily with a suit, chinos or a roll-neck jumper, without ever dominating the outfit. Those unfamiliar with the Speedmaster simply see an elegant chronograph; those in the know recognise straight away a 39 mm automatic Speedmaster designed for daily use. Then the pace of the day picks up: calls, meetings that overrun, appointments that follow one another. You start the chronograph to time a journey, a presentation or a commute; you check the calendar indications before signing a document or fixing a date. The watch becomes a discreet tool in the service of real life, sitting quietly on the wrist while you get on with what matters. In the evening, when you leave the office for dinner, a train or a drink on a terrace, there is no need to change watches: this date Speedmaster remains sober enough for formal settings and technical enough to retain its character, always with that quiet assurance of a piece built to last. That is the real strength of this reference: a very complete watch in terms of functions, yet never ostentatious.

The automatic triple-date Speedmaster: the Speedmaster spirit in a city-minded guise

The Omega Speedmaster is first and foremost known in its hand-wound Professional guise, tied to the history of space exploration. But from the 1980s and 1990s onward, Omega developed a family of automatic Speedmasters, often in 39 mm, with date or triple-date versions designed for a more urban, everyday life.The Speedmaster Date Ref. 3513.50 sits squarely in this lineage. It retains the classic Speedmaster design language – asymmetric case, chronograph pushers, tachymeter bezel – while adding a complete calendar. It is aimed at those who like the idea of wearing a Speedmaster but also want to see day, date and month at a glance, without sacrificing legibility or the comfort of an automatic movement.In 1998, the year of this example, the automatic triple-date Speedmaster had fully earned its place in the Omega range: it was the watch of the travelling professional, of the enthusiast who wants a versatile everyday chronograph, of the aesthete who enjoys the Speedmaster signature without necessarily seeking a purely historical Moonwatch. Today, these 1990s date Speedmasters are especially appealing for this balance: modern enough to be reassuring on the wrist, yet old enough to offer a subtle vintage charm.

This Omega Speedmaster Automatic Date Ref. 3513.50 is built around a 39 mm stainless-steel case, an ideal size for a watch intended for daily wear. The diameter gives clear presence on the wrist without becoming bulky, making it a comfortable option both for a man’s wrist and for a woman who likes characterful watches. The case keeps the typical asymmetric Speedmaster profile, with crown and pushers protected by graceful shoulders.The steel tachymeter bezel continues this signature: graduated to measure speed and cadence, it differs from the classic black insert by offering a more discreet look, visually continuous with the case. On the wrist, it makes this Speedmaster a touch less overtly sporty, and therefore naturally more versatile and easier to wear with formal clothing.The black dial organises the wealth of information with real discipline. The chronograph function is laid out in its dedicated sub-dials, combined with the date display (day, date and month) that remains readable at a glance. The contrast between hands, markers and the dial ensures excellent legibility, even as light levels fall. Despite the density of indications, the watch remains surprisingly clear – one of the great successes of this generation of automatic Speedmasters.Inside beats an Omega automatic chronograph movement Omega C-1151 with date, based on a robust cam-operated architecture. It combines the convenience of self-winding with the rich function set of a complete calendar. You get a watch you can wear often, that winds itself on the wrist, and that only requires occasional adjustment of the calendar at month-end. It is reliable, regular and engineered for long-term use, provided it receives the usual periodic servicing.

Water resistance is calibrated for everyday city-use: rain, splashes and normal daily life, assuming sensible care with a watch fitted with pushers. This is not a dive watch, but a robust city and travel chronograph, which does not need to be taken off at the first sign of bad weather.The watch is fitted with its original stainless-steel bracelet with adjustable folding clasp, whose solid links give a pleasant sense of substance while remaining supple enough to move naturally with the wrist. The adjustable clasp makes putting the watch on easy and allows fine tuning for comfort throughout the day. In everyday life, this 39 mm date Speedmaster behaves like an ideal working watch. In business mode, it sits happily alongside a suit, shirt, blazer, chinos or a fine knit. The black dial remains classic, the steel bezel avoids the stronger contrast of a black insert, and the compact 39 mm case means it slides neatly under a cuff. The overall impression is of a serious, technical watch that never feels aggressive or flashy. For anyone managing a busy schedule, the combination of chronograph and a date becomes a real asset: you time an interval, check the date, confirm the day and the month without reaching for your phone. The watch becomes a quiet ally in everyday organisation, as practical as it is enjoyable to use.At the weekend, with jeans, a T-shirt, knitwear or a light jacket, the Speedmaster triple date retains the same ease. It is slim and balanced enough not to feel heavy, yet sporty enough to keep that Speedmaster soul. When travelling, it comes into its own: you keep track of the calendar, time a flight or a journey, or a training session, all while wearing a watch that does not draw undue attention yet clearly has something to say to those who notice it.

That is its true territory: a watch that is very complete in terms of functions, yet discreet in its expression, one you can wear every day without tiring of it. A Speedmaster to live with, not just to admire.

The example offered is an Omega Speedmaster Automatic Date Ref. 3513.50 from 1998, with black dial, steel tachymeter bezel and its original stainless-steel bracelet with adjustable folding clasp. The watch is in very good overall condition, consistent with a carefully worn piece from this period. The 39 mm case retains clean lines and attractive contrasts between polished and satin-brushed surfaces. The steel tachymeter bezel is in good condition, showing only fine micro-marks typical of normal wear. The black dial and hands show excellent visual harmony, with no distracting flaws to the naked eye. The crystal is clean and suitable for calm day-to-day use. The original steel bracelet has coherent tension with no abnormal stretch, and the folding clasp functions perfectly.
