Rolex Datejust 36 Ref. 1600 (1973) – Two-Tone with Mosaic Dial

The Rolex Datejust Reference 1600 from 1973 in two-tone (Gold/Steel) is one of the classic variants of the early Datejust era. Particularly noteworthy in this case is the rare "Mosaic" dial, which gives the watch a distinctly unique and collector-worthy appearance.

The watch was freshly serviced in June 2026 and accordingly shows very good technical values and stable timekeeping performance.

Case & Overall Appearance

The case is in very good condition and has been professionally refurbished. The typical shape of the early Datejust references is well preserved, without the proportions appearing overly smoothed.

The two-tone look of steel and gold gives the watch the classic 70s character that still makes these references popular today.

Dial

The golden Mosaic dial is the visual highlight of this watch. This structure is significantly rarer than classic sunburst or standard dials and creates a special depth in the play of light.

In combination with the two-tone bezel, a very characteristic vintage look is created.

Movement

Inside, the proven Rolex Caliber 1570, one of the most robust automatic movements of its time, is at work.

The measured values after the revision:

• Rate deviation: +10 s/day
• Amplitude: 242°
• Beat error: 0.1 ms

The movement thus shows solid and stable performance values for a freshly serviced vintage watch.

Bracelet

The watch is fitted with a new, subsequently fitted gilded aftermarket bracelet. This is in very good to near-new condition and emphasizes the visual impact of the watch, but does not correspond to the original Rolex bracelet of the reference.

Service & Condition

The watch has been extensively serviced and refurbished:

• Movement overhauled and regulated
• Case and bezel professionally refurbished
• Acrylic crystal polished

It thus combines vintage character with improved everyday usability.

Conclusion

This Rolex Datejust 1600 offers an interesting combination of:

• classic vintage design of the 1970s
• rare Mosaic dial as a collector's feature
• freshly serviced, well-running Caliber 1570
• visually very striking two-tone appearance

An attractive vintage Datejust with a special dial and good technical condition – particularly interesting for lovers of unusual dial variants within the classic Rolex aesthetic.
