PrimeTimepiece has eight Bonest Gatti skeleton watches in stock right now, priced from $259.99 to $432.99, each showing some or all of its movement through the dial. No single listing sorts them by what actually separates one from another. This guide lines up all eight Bonest Gatti skeleton watches by case thickness, case material, strap and water resistance, so you can pick the right BG model instead of guessing from one marketplace photo.
Verdict: buy a Bonest Gatti skeleton watch if you want the movement on show from the dial side — then pick by case thickness, strap type and water resistance, not by photo alone.
Best for slim wrists: BG9601, $417.99 — 42.5mm and only 10mm thick, with sapphire crystal and 5 ATM water resistance.
Best on a steel bracelet: BG8003, $306.99 — the highest water-resistance rating of the models here, at 10 ATM, with sapphire crystal.
Best budget pick: BG5808, $259.99 — the cheapest of the eight, also on a steel bracelet, rated to 5 ATM.
Honest flag: only two of the eight models here — the BG8003 and BG5808 — come on a steel bracelet; the rest are rubber. Check the strap column in the table before you commit to a price.
Which Bonest Gatti skeleton watch is the thinnest: BG9601 or BG6601?
The BG9601 and BG6601 are the thinnest Bonest Gatti skeleton watches in this lineup, both built on a 10mm stainless steel case versus 12mm on the other six models here. The BG9601 is the smaller of the pair at 42.5mm across; the BG6601 is 45mm. Both carry sapphire crystal.
At 10mm, both sit noticeably flatter than the 12mm case shared by the BG8003, BG5808, BG7701, BG9980, BG5807 and BG9905. A thinner case sits lower on the wrist and is less likely to catch on a cuff — the main practical reason the thickness number matters at all. The two thin models aren't the cheap option here, though: the BG9601 runs $417.99 and the BG6601 runs $432.99, both toward the top of this range. Despite sharing a case thickness, their water resistance differs — 5 ATM on the BG9601 against 3 ATM on the BG6601.
Which Bonest Gatti skeleton size fits your wrist?
Three models come in under 45mm: the 42mm BG5808, the 42.5mm BG9601 and the 43mm BG8003. The other five — BG6601, BG7701, BG9980, BG5807 and BG9905 — are all 45mm. As a rough rule, 45mm reads large on wrists under about 7 inches (18cm), so start with the three smaller models. The catalog doesn't list lug-to-lug length, so compare against a watch you already own.
Steel case or glass case: which Bonest Gatti skeleton should you buy?
Six of the eight models here use a stainless steel case — the BG9601, BG6601, BG8003, BG5808, BG7701 and BG9905. Two, the BG9980 and BG5807, use a case the catalog lists simply as glass. Steel is the material behind both bracelet options and every model here rated above 3 ATM.
The exception inside that steel group is the BG6601, which is steel but rated to only 3 ATM — the same rating as both glass-case models, despite sharing its 10mm case and sapphire crystal with the 5-ATM BG9601. So steel alone doesn't guarantee a higher water-resistance number here; check each model's own rating in the table below rather than assuming by material. The BG9980 ($383.99) and BG5807 ($357.99) are the only two glass-case models, and they sit in the middle of this range on price rather than at the bottom. We don't have independent durability data comparing the glass case to the steel case, so we won't tell you one is tougher than the other — only that the catalog draws the material distinction, and that both glass models are capped at 3 ATM.
One more thing worth clearing up: you'll find Bonest Gatti described as a Hong Kong brand on some marketplace listings and as Chinese-made on others. Our own catalog data doesn't state a country of manufacture for any of these models, so rather than guess, we're leaving it out — treat any country claim you read elsewhere as unverified.
Do Bonest Gatti skeleton watches have sapphire crystal?
Five of the eight models here carry "Sapphire" in their own catalog title: the BG9601, BG6601, BG8003, BG7701 and BG5807. The BG5808, BG9980 and BG9905 are titled plainly as "Skeleton" watches with no sapphire callout, so their crystal isn't confirmed as sapphire — don't assume every Bonest Gatti skeleton watch gets one.
Because the line mixes crystal types, check the exact model title before you buy rather than assuming from the family name. Our explainer on sapphire vs mineral crystal covers what that difference means day to day. Buying from a page that lists all eight models side by side, with each one's own stated crystal, is the more reliable way to confirm what you're getting before checkout.

How do the 8 Bonest Gatti skeleton watches compare?
Price across this skeleton lineup runs from $259.99 (BG5808) to $432.99 (BG6601), and price doesn't track the specs neatly: the $396.99 BG9905 and $383.99 BG9980 cost more than the $306.99 BG8003 without its sapphire title or 10 ATM rating. The table below lines up diameter, thickness, case material, strap, water resistance and price for all eight models so you can filter by whichever spec matters most to you.
| Model | Diameter | Thickness | Case | Sapphire? | Strap | Water resistance | Price | Who it suits |
|---|---|---|---|---|---|---|---|---|
| BG9601 | 42.5mm | 10mm | Steel | Yes | Rubber | 5 ATM (50m) | $417.99 | Slim wrists wanting the thinnest case plus sapphire |
| BG6601 | 45mm | 10mm | Steel | Yes | Rubber | 3 ATM (30m) | $432.99 | Larger wrists who still want a thin case |
| BG8003 | 43mm | 12mm | Steel | Yes | Steel bracelet | 10 ATM (100m) | $306.99 | Bracelet buyers wanting the highest water resistance here |
| BG5808 | 42mm | 12mm | Steel | Not stated | Steel bracelet | 5 ATM (50m) | $259.99 | Budget bracelet buyers |
| BG7701 | 45mm | 12mm | Steel | Yes | Rubber | 5 ATM (50m) | $309.99 | Cheapest sapphire-titled pick on rubber |
| BG9980 | 45mm | 12mm | Glass | Not stated | Rubber | 3 ATM (30m) | $383.99 | Buyers who want the glass-case look |
| BG5807 | 45mm | 12mm | Glass | Yes | Rubber | 3 ATM (30m) | $357.99 | Glass case with sapphire confirmed |
| BG9905 | 45mm | 12mm | Steel | Not stated | Rubber | 5 ATM (50m) | $396.99 | Steel case buyers not needing sapphire confirmed |
If you only read one row: buy the BG9601 for the thinnest, smallest, sapphire-confirmed option at 5 ATM; buy the BG8003 if a steel bracelet and the highest water resistance here matter more than thickness; buy the BG5808 if price is the deciding factor.
Which Bonest Gatti skeleton watches come on a steel bracelet?
Only two of the eight models here ship on a stainless steel bracelet rather than rubber: the BG8003 ($306.99, 10 ATM) and the BG5808 ($259.99, 5 ATM). Both also use a steel case. The remaining six — including both 10mm-thin models — come on a rubber strap instead.
If a bracelet is non-negotiable for you, that narrows the field from eight models to two immediately — and both sit at the affordable end of this range, at $306.99 and $259.99. The BG8003 adds sapphire crystal and the highest water-resistance rating in this lineup; the BG5808 doesn't list sapphire but costs $47 less and still carries a 5 ATM rating.
Can you swim with a Bonest Gatti skeleton watch?
If you swim often, the BG8003 is the one to pick: it is rated 10 ATM. The BG9601, BG5808, BG7701 and BG9905 are rated 5 ATM, generally fine for a light surface swim. The BG6601, BG9980 and BG5807 are rated 3 ATM, which by the usual rule of thumb means rain and splashes, not swimming. These are brand-stated depth ratings rather than independently tested swim certifications, so treat the number as a guide, not a guarantee.
A higher ATM figure generally points to a better seal against water and moisture, which is part of why the BG8003's 10 ATM stands out in this group — but Bonest Gatti's own spec sheet is the only source for every one of these numbers, including that one. None of the eight models here lists a diving certification, so we're not going to describe any of them as dive-ready regardless of the ATM figure on the spec sheet. For what a 50m rating means in practice, see can you swim with a 50m watch?
Who should skip a Bonest Gatti skeleton watch?
Skip a skeleton dial if legibility at a glance matters more to you than looking at the movement — the open-worked construction competes with the hands for your eye. Skip the glass-case BG9980 and BG5807 specifically if higher water resistance matters more than style; both sit at 3 ATM, well below the BG8003's 10 ATM.
