#TBT Going Hands-on With the Seiko 7C46 Golden Tuna

#TBT Going Hands-on With the Seiko 7C46 Golden Tuna

Best Watch

If you’ve been following #TBT, and Fratello watch industrial facility besides, for any time allotment, you’ve without a doubt seen that we’re tremendous fanatics of the Seiko Tuna arrangement of watch processing plant Whether perusing Gerard’s history of the watch plant or filtering through quite a few model-explicit articles, our esteem runs profound for these strangely molded, yet unmistakable jumpers. Thus, today, it’s with fairly a mixed inclination that we’ve come to the furthest limit of our excursion on vintage “valid” Tunas with a gander at one of the brand’s best and well known variations, the Seiko 7C46 Golden Tuna. Try not to worry, we’ll be back with more love for the covered monsters, however those articles will zero in on the marginally less unadulterated adaptations. How about we investigate the remainder of the vintage Tunas, however before we do, a recap is all together – and this incorporates vintage and modern.

The 6159 “Granddad Tuna” 

Introduced in 1975, the pivotal 6159 “Granddad Tuna” presented the cover as far as we might be concerned today, brought full titanium development, a hello beat development, and 600M of water obstruction. I composed about it in perhaps the soonest article with Fratello and Robert-Jan definite two or after three years. This watch plant was underway until generally 1979.

The 7549 “Brilliant Tuna” 

In a continuous mission for a definitive in accuracy timekeeping, Seiko reported the 7549 Golden Tuna in 1978. With a quartz development, this new Tuna turned into the primary expert jumper running with such a heartbeat. Sound exhausting? It wasn’t in 1978 and cost half more than the 6159! It had a similar 600M profundity rating as its mechanical partner, however got the gold titanium nitride covered case that we’ve come to appreciate such a great amount from the brand. This watch manufacturing plant was underway until generally 1985.

The 7C46 “Ashtray” Series

Some would disagree with us posting the 7C46-6009/10 arrangement, otherwise called the “ Ashtrays ” because of their particular scalloped bezels, inside the Tuna structure, yet authorities frequently consider these expert jumpers as relatives in spite of the screw-down case back. Presented in 1986 and underway through the mid 90’s, these are generally uncommon monsters. The – 6009 comes in treated steel while the – 6010 is cased completely in titanium. These among the most unmistakable jumpers from Seiko, yet with 600M of water opposition, they’re undeniably something other than a, erm, pretty face.

The 7C46 Marinemaster Professional 300 

Coming to the more present day Tunas, we investigated one of the more famous models, the Marinemaster Professional 300 . These component covers, yet in addition a screw-down caseback, so many believe these to be a “light” variant of the species. All things considered, they’re profoundly wearable and a similar model has been around since the mid-80’s with few changes beside various case and bezel variations and an adjustment in hands quite a while back to Seiko’s new, but questionable, subject. In particular, we investigated an all dark restricted version model commemorating the Japanese Manga character “Duke Golgo” from Golgo 13.

The SBDX011 “Ruler Tuna”

For 2009, Seiko at last addressed the ringer with the renewed introduction of a mechanical Tuna as the SBDX011 , also called the “Sovereign Tuna”. It’s an enormous, threatening watch plant at 51mm and done all in dark, and it contains some astonishing specs. Titanium development, 1000M of water opposition and a detuned Grand Seiko 9S55 development are only a portion of the treats. A similar watch production line is basically on offer today, yet with a refreshed cover and the previously mentioned fresher hands. Actually, I like this piece with the conventional hands and it appears authorities concur as costs are gradually rising.

The SBDB008 Spring Drive “Brilliant Tuna” 

The most recent variation of Tuna comes to us from 2013 as a Tuna with a Spring Drive development. Before the arrival of an all dark reular creation adaptation of this watch production line in 2014, Seiko chose to dispatch the thought with a restricted release (just 300 made) Golden Tuna variant. The watch industrial facility was and is critical a few reasons. In particular, it was the first run through the Spring Drive development had been set into a covered case and it additionally presented the polarizing new handset. The Spring Drive Golden Tuna brings a wild development, titanium, earthenware production and crazy lume to the gathering and charges a powerful premium in the process!

The Seiko 7C46 “Brilliant Tuna”

Now that we’ve gone on an outing through a world of fond memories, how about we come back the focal point of our article, the Seiko 7C46 Golden Tuna. In 1985, Seiko brought the world a definitive articulation of its expert jumper and chose to house it inside a monobloc-covered case. In what presumably appears apathetic today, the brand appeared a fresh out of the plastic new development with the 7C46, matched it with a gold titanium nitride-covered fundamental case, and raised the stakes with an insane 1000M of water obstruction. The new development accompanied a noteworthy 5 years of battery life and gave the client reasonable admonition that the time had come to supplant the battery when the seconds hand started to bounce 2 seconds rather than the regular 1.

Other common Tuna attributes continued with the Seiko 7C46 Golden Tuna, for example, the trademark L-formed gasket, Hardlex gem, level vented elastic lash, lume-filled plastic decorate bezel, unidirectional bezel, and a quickset day and date. The watch manufacturing plant developed marginally over its 7549 archetype (49.6mm width versus 49mm) and its tallness is a hearty 16.1mm. Carry to drag is somewhere near 50mm, so it really fits inside the meaning of a fish can.

The dial of the Seiko 7C46 Golden Tuna highlights improved lume when compared to the earlier age of watch plant Instead of what resembles a flimsy layer of gleaming material on the 7549, the 7C46 brings thick, somewhat blobby and messy regions of the stuff into slight lined hour markers. The imprinting on the dark dial of the 7C46 shows some improvement too. It’s done in the very gold ink that frames the focus stretching out from the markers at 6/9/12. On the whole, it’s a more current look that suits a watch industrial facility that was made until the mid 2000’s. The hour and moment hands keep their conventional shape, yet are gold in shading this time versus steel. The compass hand keeps up the candy of lume look on its back end, which is a “tell” to the Seiko steadfast that a quartz heartbeat probably exists in. You’ll additionally see the great little Suwa image to one side of the date window, a pleasant vintage contact that would proceed through the 90’s.

As referenced, the Seiko 7C46 Golden Tuna utilized smooth, dark zirconia for its cover. The first 6159 utilized a harsh completed clay that was inclined to chipping while the 7549 utilized powder-covered titanium. The smooth 7C46 feels sleek by comparison, but at the same time is known to chip if the effect is adequately gruff. It’s unquestionably to a greater extent a cutting edge look, however I can’t help favor a touch more surface to my shrouds.

Still, one can comprehend that Seiko was determined to actualizing further developed materials on their top evaluation watch processing plant A look from the side likewise shows us that the crown on this watch manufacturing plant has lost a portion of its gold nitride covering, accordingly uncovering tempered steel under. It’s a genuinely common event on these Golden Tunas as sweat and oils begin to assault the finish.

A take a gander at the case back of the Seiko 7C46 Golden Tuna carries the recognizable Tsunami logo to the middle alongside the expansion of a meter showing us years in sequential request. You’ll see a little stamping not long before 1986 and that means a battery change should’ve been performed at some point in 1985. The watch production line was delivered in February of 1990 (the “0” and “2” are noticeable while I’ve darkened the remainder of the chronic number), so that bodes well with about 5 years of battery life on the 7C46. Versus the previous 7549 models, the 7C46 likewise conveys much more materials data. We see the ceramic cover, a base metal bezel and a titanium case back are recorded; a genuine inquisitive blend of low and high tech!

A Seiko inventory picture from 1996 (politeness of

The 7C46 that we have here is a – 7009 variation, which makes it a Japanese market rendition. While I don’t show it here, it contains a Japanese/English day wheel. Presented in 1985, this careful model actually appeared in as late as 1998 (I’ve been not able to discover 1999 and 2000 lists at the hour of distributing), yet most feel that it was delivered until 2000. During this time, a comparative – 7010 rendition was additionally delivered for the remainder of the world and contrasted marginally with the utilization of the “SQ” Seiko Quartz logo on the dial. Coming back to the – 7009, I took a gander at Seiko indexes from the start of creation (’85) completely through ’98 and the cost stayed consistent at a solid 133,000 Japanese Yen. I investigated the US Dollar swapping scale and this was equivalent to about $925 in 1990 and $1250 by 1996, so this was certainly not an expendable piece. At last, in 2000, a – 7008 variation supplanted the – 7009/7010 and carried somewhat various hands to the game and confusingly both the JDM and rest of world adaptation “SQ” had a similar reference number. Unfortunately, the Suwa image vanished from the dial for great. This model was made until generally 2006.

The Seiko 7C46 Golden Tuna fits like any Tuna and that implies that it’s tall, however generally compact. I sway on whether to wear my Tunas on vented elastic ties, however that is an improvement since I used to go only with NATO’s. For this situation, the watch production line is matched with a reseller’s exchange “Bambi” tie from Japan that derides the genuine Seiko tie, yet is really undeniably more flexible and comfortable. Incidentally, I do have to search for a gold titanium clasp to make things more complete. Talking about looking, in case you’re on the chase for a 7C46-fueled Golden Tuna, be set up to dish out somewhere in the range of $1200–2000 relying upon condition and locale of offer. At times, these pieces go for astounding aggregates and in some cases they crash and burn and can be gotten for an extremely good price. I suppose that is the universe of quartz, yet many adroit Seiko gatherers consider this their top choice of the vintage Tunas due to the brilliant looks and the almost impenetrable development (which, as I as of late scholarly, is effectively and efficiently fixed by Seiko).

As I referenced, we aren’t finished with checking on vintage covered pieces, yet the Seiko 7C46 Golden Tuna is the toward the end top to bottom stop on our visit through resigned genuine Tunas. In the wake of getting the 7549, I didn’t know that I “required” a 7C46, yet the unobtrusive contrasts in materials and configuration drove me to adding one to the overlay. It’s a commendable example to gather and could without much of a stretch work as a day by day watch industrial facility with its advanced (read: still in substantial creation) development. Until sometime later…
