When pricing a watch for sale, it's all about comps. We know what a 1675 is worth in all various conditions to the minutia. Speedy's- there is literally a guide to them- there is no ambiguity. The market is in tremendous flux right now so basing prices off of what we knew even last year could be very outdated- but research and logic is key to reasonable pricing.
Since nobody here is choosing to mention any specific watch, let's use one that has been mentioned obliquely as a teachable moment.
I am not trying to shame the seller- to the contrary, I hope to educate and open a discussion on how to price watches for which little information exists. The watch in question is an interesting watch, and the seller admits he knows nothing about it- but some of us know a little something about skin divers, and some knowledge of the brand (who's name sounds like an Industiral company from Pittsburgh in the 50's) and have a small (ok, maybe not small) collection of similar watches.
The brand itself is nothing special, I have followed them for some time on eBay as there are a few gems- like the one being offered in our FS section- that pop up every few months. Otherwise they are fairly pedestrian watches with chrome or gold plating, cheap but known Swiss movements and pretty boring designs. The occasional divers I've seen pop up from this brand, like the one being offered here, are similar to many of the mid-line 60's skin divers with stainless cases, Swiss movements (FHF, Felsa, AS and occasionally ETA) using off the shelf parts. Even though this brand isn't well known, the formula of the watch is.
The top of the food chain for stainless 60's skin divers were made by brands like BP, Omega (SM120) Longines etc. These are the top of the market for the style and priced accordingly. For the sake of this exercise, let's call them
Tier1.
Below that are marquis branded watches like the Helbros Invincible, Zodiac Seawolf, Wittnauer skin diver and Bulova Snorkel. These trade in the $4-700 range depending on condition (and in the case of the Helbros- orgin and changes during the run) and prices can be tracked easily these we'll call
Tier2.
Below that are quality made skin divers with stainless cases and OTS Swiss movements that were made on spec with house branding (usually for department or jewelry stores), or formerly renowned brands that are now outsourced- Traditions for Sears (Oris), Waltham, Elgin (the stainless ones) Vantage (Hamilton) Paul Peugeot, Paul Portinoux, Jules Jergensen etc. These watches are generally well made and can be a great value- typically trading for around $250-500 depending on condition, dial configuration and size. This area of the market is massive with brands nobody has ever heard of but the cases, hands, movements and dials are almost a mix and match- they pretty much all came from the same spec books and could be ordered by the gross with whatever name you wanted on the dial (Wakmann and Clebar fall into this catagory with Chrono's as an on-spec supplier as well as self-branded). These are
Tier3
Underneath that are cheap chrome plated divers. Some were nicely made with decent invexpensive Swiss movements- some have lovely dials and hand sets. But these were designed to a very low price point and meant to be fashion watches and not truly water-sport watches. They typically go for between $50-200 depending on style and condition-these are
Tier4
Below that are the single jeweled throw-away watches that have recently seen rediculous prices on eBay. I wouldn't pay $30 for these- and this running and near flawless, but apparently eBay buyers fee differently about them- I have seen these sell recently for $100-200.
Back to the watch in question- this watch falls into Tier3. It's a stainless case with unknown movement. Seller can't open the back- which is fine, not all of us have the knowledge or correct tools, but we can assume it's a mid-line Swiss movement. Case is similar to many of the tier3 divers, bezel similar to the French Helbros. Dial is unique in that it's
like an Eberhard, but it is not an Eberhard, nor was the company ever affiliated with Eberhard to any history I can find- so appearance is where the similarity ends. Hands are standard arrow hands of the period.
As for condition- case has lots of wear commensurate with a watch well worn, back is heavily worn, dial has moisture damage (some may call it patina), and lume was applied sloppily. I don't doubt the lume is original, but not a high quality application.
So we know that this watch is from a lower to mid-tier brand, it's a tier3 and is in fair condition. The dial is a unique style for the period so points added for that. Based on comps, I would put the value of this watch around $250-400. Asking $450 and accepting $350-400 would be about fair practice IMO.
Just because you don't know a brand or haven't ever seen one like it doesn't make it vaLuable. Simple research can tell you much about an unknown watch and where it fits into the maket place. Pulling numbers from the air is what outrages most collectors. We want facts, merits, comps-a rationale for the pricing.
