Rolex Datejust Wideboy 1600 1971

Grab yourself a rare opportunity to purchase a great example of an Rolex Datejust 1600 with a wide boy dial. This particular watch is stainless steel automatic calendar bracelet Rolex Datejust, reference 1600 with serial number No. 27793##. This movement number dates this watch to circa 1971.

The wide boy Dial. What is that? The dial is of the "Wide Boy" type (extra clear and wide index blocks and matching hands) and is very popular among the collector of vintage Datejust. The "Wide Boy" dials were introduced to the market in the late 1960s and early 1970s.

Besides the wide boy dial this Datejust also has an Rolex oyster bracelet. It is an 78360 Rolex bracelet with a later clasp with code G dating to 1982

 History about the Datejust 1600 series

The Datejust has set the bar for luxury watches since 1945, when this Rolex© marvel became the archetype for the modern watch. Inspired for and by the ocean, the Datejust’s revolution was a fully waterproof, automatic chronometer framing a date in the window--the first of its kind the world ever knew. This Datejust’s elegant design features a dazzling silver dial with rose golden hour marker and rose gold hour hands, and the scratch-resistant crystal’s cyclops eye makes it one of the world’s most recognizable watches. The Oyster architecture constitutes a 36mm case and bracelet which seals the timepiece’s dignified look.

The 1960s saw Rolex working to secure their place at horology’s top table, with an increasing focus on the sort of small, incremental changes to their range that all add up to huge improvements right across the board.

It brought us the ref. 1680 ‘Red’ Submariner, the first in the series to include a date complication, as well as its bigger, Comex-inspired sibling, the Double Red Sea-Dweller.

Mid-decade, the ref. 1601 Datejust was launched. With a caliber upgrade from the previous Cal. 1065, it was now powered for the first time by Rolex’s own 1500 series. Built around the architecture of the base Cal. 1530, early versions used the Cal. 1560, and received a further update in 1971 with the Cal. 1575, which brought with it the convenience of a hacking function.

While neither movement was outfitted with a Quickset mechanism, to give wearers the ability to change the date by using the crown, it was the 1500 calibers that introduced the cam and jewel system that created the instantaneous midnight change, still used by Rolex today.

From their first in-house series of calibers, the 1560 and 1575 were to become benchmarks in the world of mechanical watch movements, for their accuracy and resilience. Beautifully simple and extremely robust, they are highly regarded even today for their engineering excellence.

Inside this Rolex Oyster Perpetual Datejust 1601 houses a mechanical automatic self-winding Rolex caliber 1560 movement. The 1560 was the start of the second generation of the 1500 series calibers. They released this movement in 1959 and it remained in use until 1965. With a 26 jewel self-winding automatic movement, it had a Rolex p/n 7980 balance assembly with Microstella screws, a Breguet free sprung hairspring. It also had a frequency of 18,000 bph. Furthermore, the KIF Flector shock absorbers protected the 1560. Also, it used a traditional stone lever escapement and had a power reserve of 42 hours.

Rolex released this series with a date function version, the 1565, and with the addition of a 24-hour hand in the 1565GMT. Although there was no Quickset mechanism, the 1500 calibers came with the cam and jewel system. This system was able to create an instantaneous date change at midnight, still used by Rolex today.

The un-fussiness of the original, no-date movement made it the ideal caliber to sit inside the Oyster Perpetual series. This began with the ref. 1002 released at the end of the fifties. Its modest height of 5.75mm and diameter of 28.5mm, or 12.5 lignes, allowed it to fit comfortably in the 34mm to 36mm cases of the range.

Moreover, they also used this movement in two more of today’s most highly coveted vintage watches.

This particular Rolex Datejust has just undergone a full service. This work was carried out by our watchmaker using original parts.
