About the item: About the product Manufacturer Omega Model Speedmaster Caliber 321 Chronograph 39.7MM Ref. 311.30.40.30.01.001 Steel (SS) 2023 887 Ed White Movement Hand Winding Cal.321 Case Steel (SS) 39.7mm Bracelet Strap Steel (SS) 20cm ref.stz013537 [Unused] *Frame adjustment/ ※ Spare [Brand New] Accessory Box Warranty (2023) Strap Dial [Black]: Beautiful Condition [Unused] [Internal Machinery/Accuracy Confirmed] Comment The Speedmaster, which was born in 1957, is a model that has achieved numerous feats as a “moonwatch,” such as being adopted as an official NASA watch, and is Omega's main model that is still very popular today. The basic design of the Speedmaster Professional has not changed since the 4th model, including the current one, and most limited models are at premium prices. This is a heritage model equipped with a reprinted Cal.321. It is a model that Ed White wore during a spacewalk in 1965, and the base model is Ref. 105.003, which is the 3rd generation Speedmaster. Of the two types of case designs that are said to be characteristics of Omega, it is a case design from the second legendary genealogy, and the bracelet is extremely comfortable to put on, take off, and wear by reproducing and improving the caterpillar braces attached to the early model of Ref. 105.003. Currently, many brands are selling reprinted models, but Omega has reprinted and faithfully reproduced the movement rather than the exterior design. Some improvements and arrangements have been added, but the old applied logo, dot over 90 bezel, simple lugs, symmetrical case, etc. have been reproduced, and it has settled down to look like a vintage Speedmaster. Also, the big difference from the original is that it uses a see-through back, so you can see the Cal.321 movement with a high degree of perfection. The reprinted Cal.321 has been so perfectly reproduced that it is indistinguishable from the column wheel, the raised beard, the coupling clutch made of German silver, and even the color and engraving of the plating. There are some differences, such as changing to 18K Sedona gold plating from the original pure copper plating. Since each movement is assembled and adjusted by a single watchmaker, the number produced per year is very small, which shows how rare it is. Being able to see firsthand how Cal.321 works, which many watch fans would like at least once, is a supreme miracle. It's very rare, so I highly recommend it as a collection, and I think there will be more premieres in the future.
