Omega Seamaster Chronograph – Blue Dial with Calibre 861 (Ref. 145.029, Circa 1970)

The Omega Seamaster Chronograph Ref. 145.029 is a vibrant expression of 1970s design—bold, colorful, and mechanically brilliant. Housing the legendary Calibre 861, this piece merges Omega’s robust chronograph engineering with the daring aesthetics that defined an era of experimentation and innovation in watchmaking.

The Case – Bold Geometry, Unpolished Originality

The stainless steel case, measuring 39 mm, is beautifully proportioned and retains its original unpolished finish, preserving the sharp edges and distinctive tonneau-shaped profile characteristic of early 1970s Omega sports watches. The brushed surfaces and strong lines reflect the brand’s move toward modern, architectural forms during this period.

This “oversize” case wears confidently on the wrist—substantial but perfectly balanced—embodying the sporty sophistication of Omega’s design language of the era.

The Dial – Electric Blue with 1970s Flair

The factory-original blue dial is nothing short of stunning. Its vibrant tone and orange accents deliver instant visual impact, while maintaining the precision and symmetry expected of an Omega chronograph. The orange hour and minute hands contrast beautifully against the dial, while the white chronograph hands and markers ensure excellent legibility.

This playful combination of colors captures the adventurous spirit of the 1970s, when Omega embraced both functionality and expressive design. The dial remains in superb original condition—clean, crisp, and richly saturated.

The Movement – Omega Calibre 861 Chronograph

Inside beats the Omega Calibre 861, one of the most celebrated chronograph movements in Swiss watchmaking history. Introduced in 1968 as the successor to the Calibre 321, it became famous for its reliability, precision, and ease of service—earning its place in both the Speedmaster line and Omega’s professional chronographs.

This manual-wind movement, with its cam-lever chronograph system, delivers smooth operation and robust performance. The example here runs strongly and keeps excellent time, a testament to Omega’s legendary build quality.

The Details – Authentic Components and Vintage Integrity

Every element of this watch reflects its authenticity: the original Omega crown, the original signed plexiglass crystal, and the period-correct dial and hands configuration. The serial number 32,207,039 places production around 1970, perfectly consistent with the design features of this reference.

The watch is paired with a brand-new, handmade black leather strap crafted in Belgium, complementing the sporty character of the piece while offering comfort and sophistication.

Fabulously bizarre and effective
These silicone socks have to be the strangest item I have ever ordered from Amazon. However strange they are, I was pleasantly surprised with them. My order came with two pairs, and I took one pair out to wash before use. I laughed at handling them then because they were a cross between hospital socks and leftover mannequin skin…trippy. The socks dried fast, so I put on foot lotion and put the socks on. The socks are beige skin tones that cover the entire foot up to the ankle, basically booties. The silicone is very soft and makes putting on and taking off the socks easy. They are also surprisingly easy to walk around in because the bottoms have grips, again, like hospital socks. I walked on tile, hardwood, and carpet with no slipping. The booties also stayed in place with no issues. I was concerned my feet would sweat, but that didn't happen. I was able to wear them for 3 hours without sweaty feet. When I took them off, my feet were a lot more soft than before or if I had used regular socks. For reference, my feet are not terrible, but the skin around my toes is dry and peeling from my picking(gross, I know). The socks I got are a size large, which worried me because they are big, but the site said for my shoe size (9) that's what I should order, and they were right. They are the perfect size and stretchy for room. I can't believe how cool and well-thought-out these socks are, on top of working. Honestly, these are among the top 20 favorite items I've ordered from Amazon. They may look incredibly strange, and they are, but they work wonders.

Great Treat
Flavor Name: Chicken Chips, Size: 1 Pound (Pack of 1)
These are very thin and apparently very delicious as all four of my dogs LOVE them! I have very sensitive dogs that are able to digest this treat with no difficulty. The only thing I have to mention is this: if your dog is small, break the chip in half or quarters to avoid any choking. Great product!
