***PLEASE READ THIS DESCRIPTION IN FULL BEFORE PURCHASING OR ASKING QUESTIONS***

I keep re-posting this because the thread was in need of updates, but after x number of days, Watchuseek does not allow users to edit the original post (or so it seems). So this is the updated thread!



For sale is a recently-constructed Omega Seamaster 300. It comes with a like-new 1171/1 bracelet with 633 endlinks, a couple of extra winding stems, all Omega packaging and purchase paperwork, a PhenomeNato strap, and (as an extra) a vintage Helbros watch. Please review the payment and price options below, as there are a variety of combinations.


Payment & Price Option 1: $2,825 via bank wire. Includes 1171 bracelet and PhenomeNato strap. Price is non-negotiable as I believe this is a fair price given the watch being sold. This will include USPS Priority shipping. This is the mandatory method for buyers lacking references, and the cheaper method for all others hoping to save 3%.


Payment & Price Option 2: $2,925 via PayPal. Includes 1171 bracelet and PhenomeNato strap. Price is non-negotiable as I believe this is a fair price given the watch being sold. This will include USPS Priority shipping. Option available only to members with established profiles and multiple positive buying/selling references.


Payment & Price Option 3: $2,525 via bank wire WITHOUT 1171/1 bracelet. Includes only the PhenomeNato strap. Price is non-negotiable as I believe this is a fair price given the watch being sold. This will include USPS Priority shipping. This is the mandatory method for buyers lacking references, and the cheaper method for all others hoping to save 3%.


Payment & Price Option 4: $2,625 via PayPal WITHOUT 1171/1 bracelet. Includes only the PhenomeNato strap. Price is non-negotiable as I believe this is a fair price given the watch being sold. This will include USPS Priority shipping. Option available only to members with established profiles and multiple positive buying/selling references.


For the bracelet only: I am taking $300 for the bracelet. It's like new with all links and stamped 633 ends. PM me if interested.


I know there are a lot of options here, so please PM me or ask for clarification in the comments if there's anything you're confused about.


References: I ask that all buyers provide their references prior to purchase. Personally, I have many references available on Watchuseek, Omega Forums, and on eBay. Google “ffej4” to see my history on the forums, and check eBay for "TheFfej4".


Backstory & Remarks:After spending almost two months acquiring parts, I had my SM300 constructed by a longtime Bozeman watchmaker who happens to be the owner of The Last Windup. I intended to have this SM300 be my daily wearer, but I have decided to purchase a Speedmaster since. A Speedy has always been #1 on my to-own list.


I ordered the case, hand set, and winding stems from Cousins UK, the dial from WatchCo Australia, and the movement, bracelet, case screws, and case clamps from a variety of eBay sellers. Prior to construction, all parts were 100% brand new, sealed in Omega packaging. The only exception to this was the 565 movement, as it came from an old donor watch.


The Case ---------
The case has a few small lug markings from strap changes. The bezel clicks are firm and precise with virtually no side-to-side play. The insert is slightly off-centered (this is a common phenomenon with these SM300 service cases). Other than these notes, the case is essentially flawless with the sticker still on the caseback.


The Bracelet ----------
The bracelet is a full length, like-new Omega 1171/1 bracelet with stamped 633 endlinks. With all links installed, this bracelet should fit up to a 7.5" wrist.


Included with this sale will be my 20mm Bond PhenomeNato strap. I love this strap, and the only reason I'm including it is (a) it looks AWESOME on the watch and (b) I have 3 more on the way!


Paperwork & Invoices ---------
I have all paperwork associated with my Cousin’s UK purchase and WatchCo Australia along with the original Omega packaging of the case, dial, and hands. The paperwork will be included with the sale, with redactions made where necessary.


The Movement ---------
The movement has been recently worked on, but the watchmaker has noted one hiccup: the date change function while the mainspring has a low amount of remaining power or when nearing midnight is finicky. Coming directly from the watchmaker, "recently it has been that if I have it on the auto-winder, everything seems to work fine. When I remove it and let it run down, it invariably will stop prior to the date flipping over [around 11:00pm]. This can happen as there is more strain on the movement to actuate the date change... but it shouldn't when there is sufficient power." I'd recommend having a watchmaker perform a full service on this movement before expecting the watch to perform with precision, especially with regards to the date function. Other than the date change issues that occur around 11:00pm, there are no other notable issues. On the whole, the movement is really in very nice shape – no rusting or notable damage.


From my personal inspection, I have noticed that, when the watch nears midnight (around 10:30pm or 11:00pm when the date actuation begins), the movement will slow down or stop. The date switch happens with 100% success only when the watch is on an auto winder (or with mainspring power at 100%).


Closing Remarks ---------
This is as about as pristine as it gets. This watch is easily TZ 99% on the surface without factoring in the movement hiccup. The movement is in very nice physical condition, but should be serviced to ensure consistent accuracy. Note that these SM300 parts are becoming extremely difficult and expensive to acquire, and once the remaining parts have been bought off of the free market, these "NOS" (more accurately "service") SM300s will no longer be a viable option for the general public.
