Rolex ref 1625 yellow gold steel vs Rolex 1601-5 rose gold steel

Rolex 1625 vs 1601-5. My collection of Rolex Datejust has started to gain momentum. I couldn’t not resist the temptation in getting another Rosegold & steel Datejust as it has a rare pink salmon dial.  

This is an Oyster case with fluted 14K pink gold bezel and acrylic crystal. With original pink dial with applied pink gold applied indexes and pink baton hands. Powered by self winding caliber 1570 movement with sweep seconds and date. With Rolex stainless steel and 14K pink gold rolled link Jubilee bracelet with deployment clasp. Matching the bezel, crown, and center links of the bracelet, is the rare pink dial.

Rolex ref 1625 Thunderbird

This is a Rolex 1625 Thunderbird from 4th quarter 1965. The 1625 model in my opinion is the undervalued watch when compared with the Rolex 1601 Datejust. It has a rotating bezel versus a fixed bezel from the 1601. It is a good hybrid between the dress watch and the Rolex sports model

Muammar Gaddafi took over Libya in 1969 in a coup when he was only 27 years old. He ruled Libya for 42 years. We see Muammar Gaddafi in the photo below from 1971 wearing his Rolex Datejust Thunderbird 1625

Turn-O-Graph timeline from the forum

1952-1953: Ref. 6202 debuts, the first Turn-O-Graph. While the steel model resembles the soon-to-be-released Submariner, the two-tone model has a gold bezel that most associate with the later "Thunderbird" models. A few 6202's are named "Monometer."

1953-1956: Ref. 6309 ditches the Sub-style bezel in favor of the gold "Thunderbird" one. Full gold is now an option, as is a left-hand crown.

1956-1959: Ref. 6609 is "basically the same as 6309 but with updated 1065 movement (based on the cal. 1030 but with date)" This is the model that sparked the nickname "Thunderbird" because Rolex famously gifted some to the USAF Thunderbirds.

1957: Ref. 6602, a rare Datejust model called the "Transcontinental," is the only Rolex ever made with a 12-hour rotating bezel.

1959-1976: Ref. 1625 gets a movement upgrade to the Caliber 1500 series. At first it sports a 1565 movement, with 26 jewels vibrating at 5 beats per second. Starting in 1965, the 25-jewel 1575 movement ups the rate to 5.5 beats per second while increasing the power reserve from 42 to 48 hours. The Rolex 1625 is slightly smaller than the 1601 Datejust and the dial is also very slightly smaller and is not interchangeable. 

1977-1987: Ref. 16250/16253/16258 gets a movement upgrade to Caliber 3035, now vibrating at 8 beats per second like modern Rolexes do.

1988 - 2003: Ref. 16263/16264 gets upgraded to a sapphire crystal and Caliber 3135 movement. No more in solid gold.

Marvin Flying Dutch Man watch

A Marvin “Flying Dutchman” wrist watch, circa 1955

The “Flying Dutchman” was named after KLM, the Royal Dutch Airlines, chose Marvin for their official timepiece. The model was first designed and produced in 1955 and the watch and airline were cross marketed. The Flying Dutchman was in honour of the long distance planes used by their new partnering airline. In addition to a name that evokes a sense of adventure, the official watch line itself boasts sleek and graceful lines. The wristwatch was designed for the pilots and a clip version, similar to the tyre watch in fact, was designed for stewardesses as both functional accessory and a conversation piece.

The watch has a calibre 560 hand-winding movement, 17 jewels, three adjustments. The watch itself measures 33 mm wide excluding the winding crown and 32.5mm high excluding the lugs. The case is gold capped which means a thick layer of gold has been applied to the front of the case. The stainless steel case back is signed with the Marvin name. Dauphine shaped hands, centre seconds hand and outer minute markers.

I have seen this watch in Mr. Chen's shop and finally have a chance to trade with it using an Omega.

Vintage Moonphase watch

This is a vintage Triple calendar Moonphase watch from the 1950s. Besides Herald brand, it also has Herala and Pierce brand. It was common for brands to share similar movement, dials and case during the 1950s. What made this moonphase watch unique is the dome shaped crystal and the vintage feel of the watch plus a smiling moon.
